Here’s a few comments from Tech’s Alumni Network and Michigan Tech Parent Facebook groups

Friends and fellow MTU grads, BMS has a number of very good opportunities for staff and leadership positions. I have found BMS to be a positive, engaging company with a great mission. Is it time for you to consider a career in Syracuse, NY? I hope you do! BTW, before I joined, several people warned me about the amount of snow they get in Syracuse.  I tried not to laugh…

Back to school time again…so I’d thought I would share this example of when you are a Freshman and walk into MEEM 4220 instead of ENG 1101 somehow.
Still remember that feeling of buying the special paper (isometric dot paper) for the ENG classes and feeling like I had finally made it (get to do “real” design stuff!!)

Assistance needed. I’m a 2016 Army ROTC grad stationed in Hawaii. I ran into a 2006 Airforce grad, and only got his first name, “Scott.” He paid for my breakfast and left. Would anyone know who this is?

So excited to finally see our paver by the clock tower!!!  My son just sent us this photo. On our way up this weekend to see in person! So proud to be a Tech mom and wife.

From the Tech inbox

Moving into McNair (then named Co-ed Hall) in the fall of 1968, the east wing was only finished on the top two floors and the elevators weren’t working yet.  My room was on the top floor so we had to schlep everything up the six flights of stairs. And, even though it was late September, it was warm so the heat in those stairwells was quite oppressive. -Kerry Irons  ’72; ’73

There was something magical about Houghton and Dad’s years there that were absolutely transforming. Incidentally, Dad is being buried in his Michigan Tech sweatshirt! -From the daughter of Evans Foertmeyer, Class of 1945 on the death of her father.

I grew up in northern Wisconsin and knew I wanted to be an engineer so it came down to either Michigan Tech or the University of Wisconsin. The first time I saw the UW campus was a week after the Armstrong brothers blew up the Army Math Center on the campus in 1970. Seeing all the destruction convinced me Tech was my choice.

Scholarship and location. I applied to a few colleges but my top two choices were Michigan Tech and University of Miami. Worlds apart. But Tech offered me a great scholarship and I already was a Yooper so the snow was just a normal part of life. It didn’t hurt that the girl/guy ratio was 4 to 1 in 1977, but when most of the year is cold and snowy, it is hard to tell under a parka, boots, scarves, and mittens who was who. I have wonderful memories of my time at Tech. Very happy with my choice.

Yvette Klooster, Class of 1981

I financed most of my college expenses and chose MTU because it was a respectable Engineering University and I was blessed with a significant 4 year scholarship. Being an outdoorsman, I also liked the challenges of snow and cold. My number one choice was Notre Dame University School of Civil Engineering, but decided it was not affordable. Don’t regret my decision and still root for both schools. Earned a MBA at CMU, but not as memorable as my undergraduate experiences at Tech.

I was raised in that Tech snow. I was one of the “Local Macki’s” that frequented the back of the cafeteria in the basement of the Union Building. I wanted to go into computers since in grade school. Unfortunately, Tech did not offer such a degree in the early 1960s nor did a lot of major universities, including the University of Michigan. I settled for a Math degree at Tech and went on to learn almost all computer stuff on the job or a course now and then.

If you disregarded the 1-credit course using the Bendix G-15 digital computer that used paper tape input and a rotating drum main memory and the souped-up analog computer course, there were no computers at Tech. In fact, in my long career at technical labs and businesses, I NEVER EVER saw another analog computer.

I have accepted this lack of computing resources because Tech and a BS in Math was all that I could afford while living at home and paying my own way via a student job at Tech paying $1.25/hour. In fact, a less than $1,500 investment in tuition, fees and books turned out to be the very best investment that I ever made! Thank you Michigan Tech!

Funny story… I was interested in MTU because of its good reputation, and I wanted to pursue engineering. I incorrectly thought it was near Houghton Lake. By the time I found out just how far away it was it was too late! Super happy that I went there anyway

Andrea Cole, BSEE ’90

As the 1967-68 school year rolled forward, I was faced with selecting the college I would attend after high school. I was interested in engineering—I was good at math and science, and my father, who worked in a factory, kept telling me engineers make all the money.

I really didn’t have much of an idea of what engineers actually did, though. It just seemed like the thing I was supposed to do.

I considered four schools: Rose (now Rose-Hulman in Indiana), Northwestern, Michigan, and Michigan Tech. Rose and Northwestern were just too expensive, even if I got financial aid. When I went to college night at my high school, the recruiter from Michigan made it really clear he didn’t care one way or another if any of us wanted to go to Ann Arbor. They had plenty to choose from. But the Tech recruiter was engaged, enthusiastic, and tried hard to convince me that Tech was a great place.

I was also a hockey fan, and, as best you could from suburban Detroit, I looked for their scores in the newspaper. Plus, it was so far away and seemed like an adventure, and almost no one else from my high school was interested in Tech. All of those factors weighed positively for a kid who wanted to escape from where he grew up. The cincher was a generous academic scholarship offer from General Motors.

So, I enrolled at MTU in September of ’68. I didn’t finish in engineering—but instead graduated with what eventually became the STC degree. I later got an engineering degree at Wayne State in Detroit, and still later ended up in Ann Arbor after all, where I picked up my MBA.

I had a very good friend in Detroit whose father went to Tech and he planned on attending. I spent the summer before college with him in the Copper Country and knew I wanted to got to Tech, too. My father taught at Wayne University and both my older brothers went to Wayne so I was expected to go there to. It took some persuasion but my parents accepted my choice. I have been forever grateful. I had a great career at Bendix Automotive Brake Systems with 48 patents in the field and felt that Michigan Tech contributed to my success.

Houghton was my hometown.

Myron H. Berry, PE ’82

I grew up in a small town in New York State and our school was pretty small, with grades 7-12 totaling about 450 people. We had 80 people in our graduating class. So I was looking for a school that was medium sized, thinking it would be less overwhelming. I also wanted a science related career and Michigan Tech had, with the exception of business, all science-based curricula. In addition, being from a pretty chilly hometown, I was fond of winter sports and loved the idea of cross country ski trails right up the hill or right outside my apartment. In short, MTU was a good fit for me in terms of size, curriculum, and amenities.

As I was a U.P. resident with a four-year full ride engineering scholarship from M.J. Bacco Construction at IMHS commencement and having an interest in Civil Engineering at Iron Mountain Senior High, I really only considered Tech (MCM&T then) primarily due to its solid and respected civil engineering reputation. I was pleased when notified of my admission and headed to Houghton for the Fall Term, 1959. The Business School’s three term B.S. Eng. Admin. Degree Program for engineers brought me back to MTU in Fall, 1967. GO TECH HUSKIES!

It started with my father attending from 1950-1954. My father, Robert (“John”) is a Civil grad who worked for many years in Michigan road building. You can see how the roads deteriorated since he retired if you come to Detroit now!

He was attracted by the Forestry program and taught me how to hunt as he was an avid outdoorsman.

I grew up near Detroit and was into cars. I was always taking things apart or making projects.  So of course my inclination was mechanical engineering. However, what really sold me was attending SYP. I think I attended 3 summers and lived in DHH or in tents while hiking Isle Royale, canoeing the nearby lakes, or orienteering around Ford Forestry Center in Alberta.

I was the only HS grad from my large HS class that year that attended MTU, but the two roommates from P-town were the best!

Of course you have to like SNOW to attend da Tech. That’s why 1978-79 was my favorite year! It snowed for a straight month and 27” over one night!

What’s not to like at MTU!  “And when we’re gone from here, all our friends will be drinkin’ all the beer!”

I spent my freshman year of college at the Calumet Campus of Purdue University in Hammond, Indiana. It was an altogether pleasant experience.

What was most satisfying about that year (1953-54) was the fact that, at long last, I was finally embarked on my journey to become a forester. I had made the decision to become a forester at about age 12. Now, I had an official letter from the Dean welcoming me to the Purdue School of Forestry. I didn’t give it much thought, I just assumed I would finish college down on Purdue’s main campus at West Lafayette, Indiana.

Spring arrived, and as usually happened, I began to think about and make plans for my summer trips with family to Upper Michigan and Cloverleaf Lake. I decided I’d do some serious exploring on my own that year, and in preparation I sent away to the Michigan Tourism Council for any maps they could provide of the area just west of the town of Watersmeet.

What I received was not the few folded maps I had expected, but a rather large, glossy magazine bearing the title “The Lure Book – The Lure of Michigan’s Upper Peninsula.” It was standard tourist fare, full of pictures of grinning city folk holding up stringers of fish and ads for resorts with names like “Svenson’s Wilderness Retreat.” I was disappointed the State of Michigan would think I was just another one of “them” (i.e., tourist), so I tossed the magazine aside.

I picked it up a few days later and casually flipped through the pages. An ad caught my eye. It was a simple, quarter-page, single color ad that bore a replica of the Great Seal of the Michigan College of Mining and Technology in Houghton, Michigan.

“Wow,” I thought. “There’s actually a college in the UP!” Somewhat intrigued by the novelty of it, I scanned the listing of degree programs offered. Down the list I went – Mining Engineering, Civil Engineering, Electrical Engineering, Mechanical Engineering, Chemical Engineering, Forestry, Medical Technology………. Wait a minute, what was that? Forestry?

At that instant, a blinding flash of inspiration descended from the heavens, accompanied by a full-throated clap of thunder. The gods had spoken. If there was a college in my beloved UP, and that college offered a degree in forestry, there was no doubt where I would be spending the next three years. Michigan Tech, here I come!

That decision turned out to be one of the best of my entire life.

The UP felt like home from day one. I even got to spend the entire summer between my junior and senior years living in Seney working on a timber cruising project. The Forestry program led by Gene Hesterberg et al prepared me well for a successful 33-year career in the Douglas-fir forests of Oregon.

First of all, thank you for continuing to send me the Michigan Tech Newsletter. I really enjoy reading it.

I graduated from Michigan Tech with BSc in Chemistry in 1993. I came to Michigan Tech in 1991. I completed my BSc for only two years because I obtained transfer credits from my 4 year Diploma study (Industrial Chemistry) at one of Malaysia’s Universities.

Staying in Houghton and downtown Hancock for two years, I gained a wonderful experience especially facing the weather. It was so cold, snowing throughout the year which is different from my country (Malaysia) which is hot and humid all the year. I also had a chance to travel to other places such as Detroit, Wisconsin, Duluth, etc during the quarter break.

During my study, American students were very friendly. I still remember when I was doing the Lab work/assignment/projects in a team of American classmates. They helped me a lot and I really enjoyed studying and working with them. I was the only international student during that time.

Since I entered directly into the third year of the BSc program, most of the subjects were very tough. However, I successfully managed to go through it with the help of the lecturers (Drs , Assoc Profs and Profs) and through discussion with my classmates as well as self study.

After I graduated, I returned to Malaysia with BSc in Chemistry and my working career had moved forward. I joined a multinational Oil & Gas Company, and several other giant companies as Chemist, Lab Manager and am now working with Oleochemical company as Section Head.

Thank you very much Michigan Tech, which has made my life very successful.

Thank you for keeping us informed of all things Michigan “Tech-ian.”

Sometimes we fail to remember those who keep us in touch with our training roots.

I do appreciate your work in this manner.

’80, ’81, ’82 and ’19 …  still a student and still learning.

In the mid-to-late 50s, the slide rule was the calculator of choice at Tech. Although a small computer found its way into the Math Department at the end of the decade, slide rules were the computer used by “Toots” and carried in a leather case clipped to your belt all day. Except when in one of Dr. McMillan’s math courses, at which time your slide rule was safely hidden in the bottom of your book bag. Math, you see, is a precise science and no estimating contraption was permitted in the good Doctor’s classes within his vision range. But, even when using 5 or 7 place log/trig tables for high accuracy calculations, the slide rule was a quick way to get an “approximate” answer to check your result. Unfortunately for the Doctor’s math classes, slide rule answer checking could only be used for homework.

My slide rule is made of bamboo – a exceptionally stable wood, very smooth sliding and a lot more elegant than the metal versions. I still have mine and after 60 years, I think I can operate most of the functions.

Pete Rankin ’59EE

I used a slide rule my freshman year at Tech. Sometime early in the fall quarter (1974) of my sophomore year I bought an HP 45. The price had recently dropped about $100 and it was only $325 or so. We were married that summer and my wife commented the day I purchased the calculator was the first night we didn’t go to bed together. I stayed up late with the calculator!

Yes indeed. Last time I laid eyes on it – sitting comfortably in the storage garage at my Portage Entry summer residence south of Chassell, alongside A Dana’s Handbook of Mineralogy and my old hand lens from Kiril Spiroff’s mineralogy class.

When I started at Michigan Tech in the fall of 1964 I had a Pickett metal slide rule with 33 scales and was a yellow-green color, taunted to be better to view than the white bamboo type. This slide rule was a gift from an aunt. No, I do not have it nor do I have my old book bag. Like all other engineering students at the time I had to take chemistry from Doc. Barry. His favorite way of arranging his multiple choice (guess) answers would be something like this:

1. A) 0.167
2. B) 1.67
3. C) 16.7
4. D) 17.3

Accordingly, you had to be efficient at scientific notation and moving the decimal point around, which I wasn’t. He should have been taken behind the woodshed and flogged. But he was a full professor and I was just a poor slob “student.”

Spring Fling. Winter Carnival. Homecoming. KDay. Share your favorite Michigan Tech tradition and why?

As an incoming freshman in Chem Eng 1968, I took a Fortran course using key punch cards (both of which were outdated by the time I graduated spring of 1972 when the IT students were using keyboard interfaces.) My freshman Introduction to Engineering course included training in the use of the slide rule which I purchased my senior year in high school for my Advanced Math and Trigonometry class for $26. (The cost of one year at MTU was estimated at $1500.)  It was a top of the line Post Versalog plastic laminated, bamboo substrate, self-lubricating slide rule with log, log-log, trigonometric, and inverse trig function scales. While the sophomore and junior year classes encouraged the use of the Fisher Hall computer for some assignments, the slide rule was the calculator of choice.  The endless hours of standing in line to use a keypunch machine or cutting holes in cards with a razor blade to make minor program corrections, or taping a keypunch divot over the top of an unwanted hole in the keypunch card and hoping the cards would not gum up the card reader and gain the deserved wrath of the IT students working the computer lab or waiting in the printout room to obtain your run-output only to find 100+ errors that needed to be corrected.  By senior year the Chem Eng Dept had invested in a dozen programmable table-top calculator/card readers connected to a computer which could perform up to 256 program steps on the cards, but even better, the system could perform do-loops, iterations, and if logic. These were reserved for seniors and grad students. The system did calculations for my Senior Unit Ops lab project over spring break that would have taken years to do by hand. My first year on the job after graduation, a fellow engineer paid $300 for the first handheld HP calculator I had ever seen, (not yet programmable) fully equipped with log, trig, root, and power functions.  That is how fast calculating power changed in just five years.

Yes, slide rules, or “slip sticks” as they were sometimes called, were THE way to get numerical results for Tech students in those days (1953-1957).

But many of us also used a circular slide rule. It provided greater accuracy because while its diameter was about the same as the straight slide rule, its longest scale was about 3 times longer (you know, circumference = pi x diameter). Using the circular rule during an exam was almost like driving a car what with all of the turning back and forth that was needed to get to an answer.

Yes I do, in fact I have two.  Hey, that even rhymes what a deal.

I just wanted to share my experiences with the last vestiges of the iconic slide rule, the original tool that defined the engineer of the 20th century.  I started my Michigan Tech career in the fall of 1973 (356WWH, Excello House), my first year in the ME program, and of course ended up in Doc Berry’s ‘make or break’ CH101 class.  We were aware of slide rules, and we all had one, and usually took it to class. As the good doctor would write equations on the board, you would look around and see the ivory-white slide rules slipping out of our green canvas book bags and their black cases, to perform the rudimentary sine, cosine, and other math computations as the good doctor filled the chalk board with the math-side  of chemistry. We all saw the syllabus and noted the tests coming our way that would define our future as the ‘Problem Solvers’ of all things mechanical, electrical, chemical, structural, mining, or computational. This also included those other core classes like Calculus(William Funkenbusch) and Physics(Dave Chimino). During Q&A about upcoming tests, the issue of using the new (but not yet embraced) electronic calculators during tests came up, and MTU professors were still apparently mulling over the question.

Eventually, Dr. Berry announced that calculators would be allowed, but that the tests would not be geared toward any advantage to those with calculators (i.e., a slide rule and a trig chart were still allowed).  Life went on, but we quickly figured out that although there was no technical advantage to ‘flipping the microprocessor switch’ vs. sliding microscopic vernierscales next to each other (in terms of test accuracy), we soon learned that there was a major time advantage to touching keys:hit ’3′, ‘enter’, hit ’5′ ‘+’=8 on the crude HP Scientific calculators of the day, not to mention exponents, cosines, or vectors (graphing waveforms was not even on our radars at that time).  So…in the interest of timeliness, we all went out and bought calculators in about a 2-month period (whether we could afford it or not), and the whole issue was moot quicker than you can say “iPhoneX”.

I eventually got rid of my plastic slide rule, but kept my grandfather’s rule he once used while attending the precursor to General Motors Institute back in an earlier part of the 20th century, just for old-time’s sake.  I kept using and buying calculators over the years in my engineering careers in electrical power, steel, aluminum, and packaging, but found I used it less and less as laptops, tablets, and cell phones were making my early seventies calculator watershed event just another chapter of technological history

My son became a Computer Engineer at Clemson U. several years ago, and had only a TI-84 graphing calculator for a short spell in high school.  I kept all my Tech course books for probably 20 years before realizing they were becoming dead weight, and my son gave away his books at Clemson prior to graduation, mentioning that everything in his text books could be found online in a matter of seconds, so why bother?

“The times, they are a changin’”, as Bob Dylan’s words used to echo throughout Wadworth Hall back in the day.

I keep my slide rule in my basement workshop. Very handy. No battery needed.

Chuck Young ‘65

I went to MTU 1968-72.  The Post Versilog slide rule was the best you could get because it was bamboo and didn’t warp.  And the round slide rules were suppose to be more accurate for the same size. When we did statistical deviation problems it was all by hand.  No calculator short cuts. And rotating a formula around an axis was all by hand, too. No graphing calculators.

We used WAT 4 with punch cards on the 2nd floor of Fisher Hall.  And if you typed too slowly they asked that you have one of their operators do the cards for you.  Of course, if you got just 1 card wrong you had to try again. Type them, submit them, and get back your cards and the results.  Go back the next day and try again. You better not put off your project ‘cause you’d never get it back in time!

And in the dorms in 1968 the only phones were at the end of the hall.  So in Coed Hall, on one floor we had 4 phones, 2 in one corner and 2 in the diagonal corner.  No privacy. By 1971 there were phones in each room on the wall.

I attended MCMT (pre MTU) from the fall of 1949 to graduation in the spring of 1951.  I think slide rules were available in the Book Store and the one I used was a Pickett and Eckel (sp) for Electrical Engineers.  At that time I think it was the state of the art and we were sure glad to have something better than looking up trig functions from a book, etc.  It became a standard item to carry around and have at hand like you would a pencil or a watch.  Can’t remember how much it cost, but probably $25 to $30  – expensive for the time. I became a Meteorologist in the Air Force so it didn’t get much use.  At some time later I gave it to my son and he wondered how we ever able to get along with such an ancient tool.  He finally had it mounted, along with the plastic case, in a glass frame  and recently gave it back. It now resides on the wall in my den where it is visible all the time.  So how did we ever manage?  I think we could could read values, with some degree of accuracy, out to maybe four places – we were always entertained when the Professor would take a six inch slide rule from his pocket and read it to six or more decimal places.  PS: I believe those two winters we had over 200 inches of snow each year.  That’s why I live in Arizona year around.

Many Blessings.

In the summer of 1959, I took a course on digital computers at “Da Tech”, when computers were only used for COMPUTING.  That is where they got their name. I believe that Dr. McMillin was the professor. A new born baby is not treated any better than the way Dr. McMillan treated “HIS” computer.

The computer was manufactured by Bendix.  It was housed in its own air conditioned room, the only one on campus, and was about the size of a small office.  It had over 10,000 vacuum tubes (prehistoric transistors) and a lot of blinking lights that no one, including the professor, knew what they meant of how to read them.  The lights were pretty and lent an aura of mystery to the room. The machine was about six feet high by five feet long by four feet wide. The input and output were either by punched cards or punched tape and performed it’s function extremely slow compared to 21st century computers.

Part of the course was learning how to program the computer in machine language.  If this archaic method were still being used for programming by the average user, we would not be widely using computers today.

The machine broke down on the average of once every couple of hours, which mostly could be repaired by Dr. McMillin.  About once every two weeks a technician would fly to Houghton from Milwaukee for a service overhaul and correct any malfunctions.

I remember one graduate chemistry student was performing some type of experiment that collected data at the rate of three points per day and required hand calculations requiring one full day to do one data point.  A person gets behind in their work real fast at that rate. With the computer and a proper punched tape, each of the three calculations could be done in about two hours of computer time, a time savings of 4 to 1. The calculations for all three data points collected each day could therefore be completed each day.

I graduated from “Da Tech” in 1962 with a BSEE and took no additional computer courses at the school.  I spent five years at my first job in Milwaukee and as far I know the company did not use a digital computer for anything.  I spent the next six years at my second job in Chicago. They did have a digital computer to calculate transmission line tower spotting, but since transmission lines were not my responsibility, I never used the computer during those six years.  It was not until I was into my third job in Rosemead, CA about 10 years, that I actually started to use a digital computer supplied by the company. They also offered numerous free on-site training classes which greatly enhanced their acceptance, even though some of the really old timers at the company never got passed the fear of turning the computer on.   And as they say, the rest is history.

Until the advent of the computers, paper and pencil, a slide rule, or a mechanical chickity-chick calculator were the method of performing mathematical calculations.

Thank heavens computers have greatly improved since those days in the late 50s and “Da Tech” has kept up with the changes.

When I was there in the late 50′s, I graduated in 1961, most used the Post slide rule. I suppose mine is still around here some place. Don’t know what I could still do with it. Some Techs liked the round metal ones. Never could see much use for them.

I remember having to hike down to the computer center located in the area under the space between the EERC and Chem-Met buildings to create FORTRAN punch card decks for computer assignments.  What fun that was! I also had a TI-58 programmable calculator. It had the worst keyboard imaginable! Keys bounced or stuck all the time. During exams, I would work problems at least twice to make sure that a keyboard issue hadn’t sabotaged my answer.

Howdy from western Colorado,

You asked if I still have my slide rule.  Answer is yes. Bought in fall of 1959. It is a long yellow metal Pickett and I have it hanging on the wall above my computer. I also still have a small yellow Pickett in my desk. Haven’t used them in a long time.

I was near the end of the slide rule era. It was probably a good thing too as a new ‘state of the art’ calculator was beyond my budget at that time.

I still have my slide rule but I really don’t remember how to use it.

Back in the late 50s and early 60s this was our calculator of choice.  I actually used it for many years after graduation because it was so fast.  I was sure that it was long gone but when I was looking for something else in a drawer in my shop today, there it was!

In ’74 I started out at MTU using a slide rule.  The expected accuracy of the results on the tests were based on the accuracy of a slide rule.  In the Spring of 1975 I bought a Bowmar MX90 for about $100. It was a huge amount of money but having the standard 4 functions plus square root, %, 1/X, and memory functions  it was a major leap forward for my classes. In the Fall of ’75, with more students having calculators, we were told the test result accuracy would begin being based on them forcing all the other people to buy one.  I continued using the Bowmar until the Spring of ’76 when I bought a TI SR-51 for about $230. Yes an even bigger amount of money (about one month of part time pay) but with complete set of scientific functions it was worth it.  I still have the slide rules (yes multiple), Bowmar and TI. A long time ago the batteries stopped holding a charge but they still work while plugged in with the power adapter.

As to computers and programming, the only class I had at Tech was Fortran in the Winter quarter 1974-75.  We used coding sheets to write our programs and we typed it onto punch cards. All the results were returned to us in the form of a printout.  Debugging the program was done reading the HEX code in the printout. If by chance you dropped your cards we luckily had card sorters that would put them back in order.

In ’78-79, when I did my senior project, the Metallurgy department received a large influx of grants to buy new equipment, some of which I got to use.  The most impressive one was the X-ray spectrometer; it was one of the first computer controlled systems and had a “large” 18″ monitor. It came with about 50+ calibration samples and since I was going to be one of the first persons to use it, I got to set up and maintain the calibration curves in the computer.

The cutting edge technology moment I remember like it was yesterday was the day I entered Fischer Hall and saw a crowd in the hallway.  As I got closer a professor was showing the group a device called an HP 35 calculator. I remember he had a leatherette holster to hold it to his belt.  The professor stated that it cost him over $300 dollars. The minimum wage in 1971 was $1.25 per hour. According to the inflation calculator $300 in 1971 equates in 2018 to $1,836.  Funny thing is a good Casio today does more than the HP35 did in 1971 and it costs $25.

I still have the POST Versalog that I used at Michigan Tech until graduating in 1961. I then used it in designing hardware for the Apollo command module fuel cell and for the TF34 aircraft engine. I also have the Hewlett Packard HP45 calculator that replaced my slide rule, and the HP48SX calculator that I finished my career with at GE Aircraft Engines in 1998. That last is a remarkable computer-in-the-hand, with a sophisticated programming language and the ability to solve nonlinear simultaneous equations.

Starting in 1970 I had a Post Versalog slide rule, made from Bamboo.  I still have it. Professor E. T. Williams gave us training on using the slide rule in our beginning Chemical Engineering course.  You know… E. T. Williams wrote the book on Chemical Engineering calculations. During my time at MTU, Hewitt-Packard came out with the first scientific calculator (HP35?).  They were like $300 and I never had one in college. One of my colleagues had one. Now you can purchase a scientific calculator for $15, or just load a free one on your Smart Phone.  We had it rough, but on the other hand beer was 35 cents a mug at The Library, or 15 cents a shell at Eva’s in Calumet.

I graduated in 1969. We used slide rules and I still have mine. We also had to do programs on computer punch cards. When I got to my first place of employment Alcoa Aluminum they had started to use computers on their production lines. The first computer that I saw on a production line was about the size of a desk and had 2k of random memory… The disk drives were about 12 inches in diameter and were  1 MB capacity,

From 1969 to 1972 it was the slide rule. Some preferred the aluminum Pickett, I had the Post Versalog II which  was made of bamboo. Still slides easily today. In 1972, HP introduced the HP-35 calculator which I first saw used for the EIT exam.

Computing technology advanced a lot in my time at MTU.  When I arrived in the fall of 1968, Tech was very proud of the IBM 360-44 which took up four classrooms on the second floor of Fisher Hall.  You could open the door to a cabinet and see the individual memory bits: a little ferrite disc with two wires connected. Massive tape machines lined the walls and all of our computer programs were done batch, on punch cards.  If you were lucky, you got to see how your program worked (mostly didn’t work) once every 30 minutes or so. And there were about 10 possible error messages to help you figure out what you did wrong. I won’t say they were useless, but they were not that useful.  There was also an analog computer that some upper class students had access to – that’s right, resistors, capacitors, and inductors you could hook together to simulate the real world and watch your solution stabilize in real time on the oscilloscope.

There were no calculators except in some engineering professor’s offices (Freiden motorized adding machines, Wang tube calculators) and there was a bit of “mine is better than yours” tussle between owners of different brands/models of slide rules.  Pickett & K&E were the big brands, and the wider your slide rule was, the more cache’ it had; a wider slide rule meant you had more scales and therefore more calculating power. A good slide rule was over $200 in today’s money. Pity the person who bought a plastic slide rule at the MUB thinking it would be sufficient to get them through their engineering/science classes.

The first HP pocket calculator appeared at Christmas, 1970 – it was $2500 in current dollars.  It could do everything a slide rule could do, carried 8 significant figures (slide rules only had 3), AND IT COULD ADD AND SUBTRACT!  The great debate as to whether to allow calculators to be used on tests began in about 1972 because by then a lot of freshmen were showing up with their electronic high school graduation presents and demanding to be allowed to use them.

By the time I finished grad school in August, 1973 there was a project underway to replace the IBM with a CDC machine that actually had terminals scattered around the campus where you could execute a program in real time.  No more spending nights in the computer lab waiting for your printout for the project due the next day. No more punch cards.

I still have my Pickett slide rule as a decoration, and I can still sort of operate it.  Those were the days.

Before I got to Tech I bought a slick Pickett and Eckel slide rule.  I never got good with that. When I took the computer course (in 63), the only communication to the computer was paper tape—with machine language.  It wasn’t pleasant.

I went to Michigan Tech with a slide rule but quickly purchased a calculator to keep up with classmates. My slide rule is in a box somewhere in my basement, but I don’t remember how to use it.

Debbie Hamm BSEE 78

I started my Freshman year in 1974 needing to take a slide rule orientation course from Dr. E.T. Williams in the ChemE department.  Fortunately, the first TI calculators and the more affordable “Bowmar Brain” $99 calculators were just hitting the market, and the slide rule was put away for good.  A student in our dorm sold dozens of TI’s at a special price from his family’s electronics store in Appleton for around $150/each. We also had to write Fortran programs and punch them out on maybe a hundred cards to run through the readers in the basement of the ME-EM Building which was one of the newer buildings on campus.  The mainframe computer was usually backlogged 2-4 hours in the evening, which was painful when one bad keystroke on one card could stop your program in its tracks. Worse yet, was watching some computer nerd’s output printing out on large lined paper that was a depiction of Alfred E. Neuman on a Mad Magazine cover done in text to hang on a wall.  Engineers had serious programming to complete, and we were in no mood for those shenanigans backlogging the computer. Nobody had a PC yet, and we all could have become infinitely rich had we known where Microsoft and Apple stock would be going!

Computer:  Apple Macintosh – had access to first one on campus and used it for a technical writing class.

Slide rule:  Was taught how to use by my high school chemistry teacher Don Seablom – he insisted that since it did not pop a number out like a calculator, that one had to be good at estimating one’s answer, first, in order to assess if one had manipulated the slide rule correctly – a skill that he knew no one used when using a calculator, and one I appreciate, still.

I graduated in 1970 and used a slide rule and punch cards on the IBM360 mainframe. The punch cards were very painful since once punched out even the slightest syntax error resulted in not being able to compile, generally you had to wait for the next evening before you could re-submit the corrected card deck.

After working about 1 year (1971) I then started using an simple HP calculator which cost about $600.

When I graduated from high school and was planning to attend Tech one of my graduation gifts was a slide rule.  It was warmly received although, I must confess, it took some time and practice to become efficient and to place the decimal point in the right location.  I have the original slide rule, as well as several others acquired over the early years. It is amazing how much easier it is for students and professionals to have the power of computers available today, and yet, how sad to see this old technology fade away.

I’m an Alum from 9/1967 to 6/1971, a four year wonder with a BS in Chemical Engineering.

A Post slide rule was my weapon of choice.  Used the IBM 360 in senior year with punch cards and Wang calculators with a central processor were installed in the Chemistry / Chem Eng. building for our use.

Man times have changed. However after 32 years at Dow Chemical I learned that the key to analysis is not the tools but the assumptions.

My cutting edge tech (class of 1960) was a slide rule, which I still have to this day. In fact I used my slide rule through most of my engineering career. I designed the electrical systems for more than 7 large power generation stations (33MW up to 600MW) with my slide rule.

Herb Little  PE, BSEE Class of 1960

________________________________________________________________________________________

In the fall of ’72 our Chemistry Recital teacher told us to buy only the cheap $3.50 plastic sliderules because they would soon be obsolete.  The only scientific calculator at the time was the HP 35, at close to $500 each, a quarter’s out of state tuition at the time.

In the summer of ’73, TI came out with the SR40, roughly equal to the HP but it had algabraic entry instead of the HP’s reverse Polish.  They sold for $145 at the time and seemed a bargain.

That fall the Campus bookstore was stuck with about a thousand of the old $25 VersaLog sliderules that nobody wanted.  In a vain belief that sliderule would come back they held on to them and refused to sell calculators for a couple years.

There were variations among professors at the time whether calculators should be allowed in tests because some kids couldn’t afford one.  Some said it was OK, others asked us to set up our work so that it could be plugged into a slide rule or calculator. By 1974 prices had fallen and this was no longer an issue.

It was a fear that the calculator battery would run out in the middle of a test.

The TI 30, roughly equal to the SR 40, is still my go to calculator and now they cost about $12 at Wally World.

The slide rules is long gone and the SR45 display failed and it was tossed.

I saw some other interesting things at Tech:

A kid walking around the dorm with the huge headphones of the time plugged into a battery powered cassette player, about 5 years before Sony came out with the Walkman.

A plotter in the computer department drawing a topographic map, very rare back then.  Watching those pen plotters was like watching a fire, it never got boring.

Some of the computer guys talking about how many of the stove size hard drives of the day it would take to store even a few minutes of live television.

I still have my book bag, though.  I use it for camera gear.

I graduated from Tech in 1957, having graduated from Hancock HS in 1953 where I got a perfect score on my final trig test, and in only half the time, using my old slide rule.  I bought a new Post bamboo slide rule for Tech. Post had just added two more log-log scales for better accuracy. Prof. Jim Oswald asked us students in communications class to use our new “high powered” slide rules for some calculations he needed during his lectures.  Chem students used an 8-inch circular slide rule for even better accuracy. There were no computers then. We were just switching from vacuum tubes to transistors.

The two most expensive Tech purchases were my slide rule and my drafting set, each costing about $38.  I still have them and use them sometimes. Books ran about $5 and tuition for the year was $123. I lived at home as a local yokel.  The picture in your email looks like me at that time. I had just got my first eye classes.

There were a few Wang (IIRC) calculators in a room in one of the upper floors of the new Chem & Chem Eng Building.  They were on security cords and could not be taken out of the room but they did do multiplication and division without having to determine where to put the decimal point which was a challenge with a slide rule.  And yes I still have my Post bamboo slide rule which works just fine.

You touched a nerve!   (Your request for “ancient history at MCM&T.”) Computers were just coming on board in the ‘50’s.   They were huge, and filled a room, with electronics, in large corporations.   And got their instructions from IBM punch cards. Thousands of girls were employed as IBM punch card machine operators. The student computer(s) of the day was/were slide rules; both linear and circular. I had a Pickett & Eckel,  Model 1000, “Duplex”. Made in Al Hambra, CA, in 1948. It was made out of Magnesium. The “good” ones were made out of bamboo, by (I think) (2) German company’s, named Dietzgen, and Keuffel & Esser. I couldn’t afford a bamboo “stick”.

I just went over to my credenza and picked it up out of a pile of stuff. It’s been untouched for some time, and the slide is corroded to the point where I would have to hammer it to break it loose. (Kinda like me!) Still in its felt liner, in its leather case. See pictures.

At a reunion a number of years ago, the bookstore was closing out its’ remaining inventory of slide rules. I bought the whole bunch, with the idea of selling them years later, to old guys like me, with a heavy dose of nostalgia. I think I gave away a couple of them. But at  a reunion, maybe (10) years ago, Georgia and I visited with Glenn (Mroz), and gave him the remainder of what I had, and told him to sell or award them to some super-dooper alumni. I have no idea what he did with them.   Maybe they’re still on a shelf in his office.   (Maybe he kept one?)

When I was an ME student from 1960-64 the slide rule ruled but we also had a magnificent computer on campus.  It looked like an old refrigerator and probably had far less capability that the calculators that can be purchased these days for less that $5.00.  It was the Bendix G15 programmed with punched paper tape.

When I entered the Class of ’78 (in September 1974), one of my first purchases at the MTU Bookstore was my wooden Post Versalog II slide rule. A year later, I entered the calculator world with a TI SR-50a.  Alas, the SR-50a has long since went to the scrap heap, but the slide rule still resides in my desk at work, and occasionally sees use – in these days, more as a curiosity than anything else. As a matter of trivia here, for those old-timers like myself, apps for smartphones and tablets are available to mimic the slide rule.

As another tidbit of information, in either 1977 or 1978, I went into the final exam for PH-310 (Nuclear Physics) with my SR-50a in hand, and with the slide rule still in my book bag.  The batteries in the calculator promptly failed, even though I had just charged it, and I completed that final exam with the slide rule. I did “show my work” more than I would have with the calculator to assure the Professor (I think that it was Prof. Devatilla – spelling uncertain – if I recall properly) that I knew how to solve the problems.

I started in 1971 and the slide rule was pretty much the standard for engineering students.  However in 1972, that changed with the introduction of the HP35, a true scientific calculator.  It wasn’t cheap though, at $395. I still have both, but the batteries have long since failed on the HP35.

One big discussion on campus among the various professors was the requirement to use slide rules.  I remember an exasperated older professor was complaining that if they did away with the requirement to use a slide rules the students would never learn to use a slide rule,  a younger professor countered with they will never use a slide rule. We never used slide rules. HP 41 C and TI 59 were the hot calculators.  My analytic chemistry professor explained how to round decimals and said the HP did correctly and TI did it wrong.    Several students with TI’s complained and wanted to argue the point. The professor explained he had a HP and his calculator was correct which ended the discussion.

In 1972, the cutting edge technology was the HP-35 Scientific Calculator – it could do square roots and powers!!!  But since it cost $375 (in today’s dollars that is around $2,200!) only the wealthy could afford one.

Good thing MTU offered a short class on how to use a slide rule.   A 4-function calculator could be had for around $100 back then (around $600 in today’s dollars), but without square root functions the slide rule would continue to rule for a while.

Brad Abel 1976

As you can see, I still have my MTU tool kit, although I haven’t used them in years.  I didn’t acquire the calculator (a Commodore model MM2) until a junior. The last time I really used the slide-rule was in 1977 when I took the Illinois professional engineer exam, and my calculator went dead.  I finished the exam with the slide-rule, and passed the exam.

Best wishes;

I started as a frosh using the slide rule and continued part way through my sophomore year using it.  I had to break down and buy a Texas Instruments SR-50 to keep up with the rest of the students. The SR-50 was the affordable scientific calculator for me as an engineering student.

Terry Rotter ‘76

During my tenure at ‘da Tech’, the most widely used ‘technology’ was the Slide Rule.  I bought a metal one because I wanted it to last a lifetime, which it has (so far). But we also had access to at least one mainframe computer, but you had to punch your own cards and wait for the print-outs.  In a couple of my ME classes we used analog computers to simulate mechanical systems. We also had access to a couple of Wang Calculators, which was a bulky desktop ‘computer’ that allowed some basic programming (an example is on display in one of those upper-floor ‘museum-like’ display cases in the MEEM building).  During my last year in school, hand-held calculators first appeared, in the form of very expensive HP-35’s. Only a few students (or perhaps their parents) could afford them. Of course, this was well before the era of CAD/CAM, so any drawings needed for a class had to hand-drawn using triangles and T-squares. All-in-all, the ‘technology’ of the day was very hands-on.

As an add-on, attached is a photo taken my senior year of our oldest son, who was 9-months old at the time, playing with one of my classmate’s slide rule.  And before you ask, despite his apparent interest at the time, he didn’t go into engineering but instead is an executive with a major restaurant/entertainment corporation.

Until grad school, we used slide rules or long hand math.  In grad school the first scientific calculators from HP came out.  However, at a price tag of $395 (then price), only some Profs had $$ for them.  That correlated to about 25% of my quarters stipend as a teaching grad student! I didn’t’ get my first scientific calculator until I had my first job in the USAF sometime late 1974.

During my years at Tech (fall of 1949 to spring of1953) the slide rule was king, and I still have mine.  The first one was a circular one. The reason I had it was the cost….a straight slide rule cost about $20,  the circular one cost $8.25. The choice was easy……l was washing dishes in DHH for half my room and board,  I watched my money very carefully. Money to buy a beer was prime! Later I was able to buy a straight slide rule second hand,  I still have that one also. I don’t use them much any more ( the calculator one my iPad works just fine!).

After graduation, a couple of years in the Army, and getting a job as a Geophysicist with Continental Oil Co.  I got heavily involved with computers…..my slide rules have gathered dust ever since.

We were just using calculators, I got one of the Sharp / RadioShack pocket computers, a lot of my friends had the fancy new HP RPN calculators.

I started on cards, worked at ACS in the batch station, dispatching output, and even as a CS major, didn’t get terminal access until after CS200!  Later on, I worked up to ACS consultant.

I witnessed the first IBM PCs getting installed at ACS, as well as the brand new tiny Macintosh computer that sat by off by itself in a room off the batch station.

People on campus were using Apple ][ computers, and I was one of the lucky ones that actually got their own computer – a Morrow Designs MD-3 Z80 machine running CP/M.

Before that we would check out a TI Silentwriter mobile terminal that we could take home to access the Univac (being an ACS consultant had it’s perks!).

This was 1980 to 1985…

I was at Tech from fall of 69 to Spring 73.  I often tell younger engineers about how we first saw hand electronic calculators near the end of my senior year and were told on the last final exams we could use one if we had one.  As I recall they only did the simple calculations of add, subtract, divide and multiply but I did not have one – they were expensive. I also recall the computer center and the punch card decks and system.  First you write your program then make punch cards and drop them at the window. Some operator would run the deck and in an hour or two you got a print out which almost always had errors. Fix the errors repeat then try to find the new errors.  Not fast and the system would drive the young kids today nuts. I still have two slide rules somewhere in my house that I used.

I saw the topic and invitation to send and email and immediately knew I had to chime in.

I started at Tech in the fall of 1990. I believe it was the first year there were calculus classes “with technology” offered. In order to enroll, students were required to own an HP-28S or HP-48SX calculator. These were quite new; the 28 about 2 years old and the 48 had just been released.

My parents bought me the 28S, it being the cheaper model. It was unlike anything I’d ever seen! The professors even had a version with a remote display that could be put on the overhead projector!

After about the first quarter, I was becoming jealous of the 48SX, as it had the ability to load programs via a serial cable. The 28 could only _transmit_ data via IR. Any programs had to be manually typed in on the keyboard. So, I sold the 28 and upgraded to a 48 and the required cable.

I used the 48 throughout my (many) years at Tech and would still have it today had it not broken in what is apparently a pretty common fashion. In it’s place I purchased a more recent 48GX. In a pinch, I’ll even revert to an emulator on my iPhone.

Oh, I do have a slide rule that I bought some years ago, but I’m not very good at using it.

Cheers!

Matthew Jachimstal ‘00

Yep!  Still have my slide rule!  But haven’t used it in years.

It is a Pickett model 1010-T trig slide rule, metal rather than wood.  Owner’s manual even tells me how to lubricate it with light oil. “Work in well by moving slider back and forth, then wipe off.  Any light oil is a satisfactory lubricant.”

Wouldn’t want to try that with a graphing calculator.

Also I still have the leather holster for my slide rule, with clip for wearing the slide rule on my belt.

Another tidbit from the instruction book: “If Cursor window becomes dulled from long use, simply polish and brighten the window surfaces with a small rag and tooth powder.”  When was the last time anyone ever bought tooth powder?

I was a freshman in 1974-75.  Hand calculators were pretty new.  I purchased a new Hewlett Packard 21 (a smallish tan and black calculator) for about $80.  You can buy a “vintage” one today on Ebay for $95 .  It featured “reverse polish notation”.  For my Engineering classes in 1977-1978 time frame, we used punch cards and fed them to the main frame.  Then waited for hours for our printout results that were handed to us over the counter.  I think there were a couple of terminals or personal computers at the University, but only the Graduate students got to use those.

Slide rule. Had both a full size Pickett and a six inch pocket version.  Remember carrying a box of punch cards to the computer lab for some VERY early training.  Praying of course I wouldn’t drop the box. I still have both slide rules and remember how to use some of the scales.  Slide rules taught us to estimate the final answer as far as magnitude goes. Problem with some younger engineers who’ve only done calculations with a computer is they don’t estimate the final outcome and believe the computer number without considering they could have made an entry error.

I graduated in Civil Engineering in 1962. Finally, one of my numerous off-spring wants to be an Engineer. My 18 year old Grandson will be enrolling this Fall, in Engineering, at Oregon State. On a recent visit to me where I live in Waldport Oregon, in 2017. I showed him my slide rule and how to do some of the more simple calculations: multiply, divide, cube, cube root, etc. He took it back with him to Texas to show and demonstrate to his Senior Math Club in High School.

I actually bought that Slide Rule before I even went to Tech. Bought it in 1957, on starting my 2 year Associate Engineering Technology Degree at a Community College in (then) Port Arthur Ontario, Canada. So that makes the Slide Rule 60 years old when I gave it to my Grandson.

I always kept it in my desk over the years and played with it once and a while, simply because I could.

After all these years, I am still an active Consulting Engineer in my chosen field (right out of Tech) of Heat Treat Equipment Design. There is no substitute for someone being able to offer experience and judgement to the newer Generation of Heat Treat Equipment Engineers.

When I finished my degree in 1979 my final senior project was done completely on punch cards.  They were free back then too, thank goodness. My project was over 2,000 lines of code and took up two full boxes.  I fed it into the card reader in huge handfuls. An occasional misread card would force me to start over from the beginning.  Lugging the cards around wasn’t much fun either, but the boxes were small enough to fit in my “toot bag”, which I still have with me.

While many of the newer students were starting to use the “green screen” terminals to enter their programs, I used the readily available punch card machines.  No waiting (usually). The terminals always had a line of students waiting to use them.

Bubbles Byers of the math department was the computer guru in the mid 50s. He was my professor in a math class and sometimes we’d meet him on the way to class except he’d be going in the opposite direction, undoubtedly to work on his computer that was probably composed of some kind of tubes. The slide rule was my “computer.” And it always worked! And we never handed in answers with 8 significant digits!

The name of the college when I started was Michigan College of Mining and Technology. Most in not all engineering students shouldered a green canvas book bag with a slide rule attached to the side. Sometime during my tenure the college name change to Michigan Technological University.

Yes punch cards were used to created computer programs and as I recall my first program was to solve the quadratic equation.

I received a Pickett slide rule from my uncle (A Chemical Engineer) for a high school graduation present.  I remember Doc Barry used a circular slide rule in freshman chemistry. I thought it was harder to keep track of the ten’s places with a circular.  In the summer between freshman and sophomore years I saw the HP35 for the first time. Bought one at the beginning of junior year when the price was lowered to $300.

“Slide Rule. Computer Punch Card.”  That was it, we did not have any more than that, my first year at Tech.  I remember my second or third year. Someone arrived at school with a four function electronic calculator.  We were amazed that something that small could do any calculations at all. But, some of us could still do simple calculations on the slide rule faster than the calculator could.  No such thing as a “TI-84 Graphing Calculator!”

I still have my Post slide rule in its leather case.  The ID window in the case still says “R241 DHH”!

Of course, my first year at MTU was 1969…..

My slide rule and Texas Instrument SR-50A calculator with a single memory.  It did trig, logs, and of all things factorials. I threw it against the wall of my dorm room in Douglass Houghton Hall following a Doc Berry freshman chemistry exam.  It still works after 40+ years! I still have a pile of those add/drop/section change computer cards too!

Rob Kuczynski ‘82

Still have slide rule, only used once in class.  It was my father’s.

Punch Card first term, Terminal After that.  Remember signing up for 2am slot to get on terminals.  Non at Co-ed Hall, but there were some in Wadsworth.

1976-1980.  I remember taking a basic language programming class. There were dec pdp 11. Teletype machines in the basement of the bus admin building.  The program code was stored on 1/2 or 1 inch paper tape. There was also a univac1110 mainframe in the basement of EERC with 80 column Hollerith punch card readers.  The punch cards were purchased by the box from the book store in the memorial union bldg. the ME-EM building had a remote station with a printer keypunch machine and card reader you could use late hours and week ends if you signed up and qualified for it.  There eventually was a room in basement of EERC across from MF room with teledyne monitors with keyboards so I didn’t need the punch cards. I also remember buying a TRS 51 programmable calculator from the bookstore. No sliderules while I was at tech

John Pozega ‘80

My freshman year began in the fall of 1968. Everyone had slide rules. I skipped the Slide Rule class as I learned that skill while in high school. I keep it as a souvenir.

For me the cutting edge was the IBM model 44/PS computer on the second floor of Fisher Hall. I took a computer class taught by researchers from Gerber Baby Foods and learned Fortran and the model 026 keypunch. The computer center gave me a user ID and I continued to learn computers on my own during those years of Doc Berry and Ted Vichich. Upper classmen sought me out to help debug their programs.

In my junior year the EE department opened a small computer center using an SDS 900 computer used to teach assembly programming and I was hired to be the tutor and operator.

Great times, those.

In the mid 80s, the hot engineering calculator was the HP-15C. You had to use reverse Polish notation for entry but it did almost everything, including the imaginary number computations common in EE math. I still have mine and even have the HP-15C app for the iPhone.

I was using my post slide rule … in it’s leather case when i got there.  (still have the slide rule hanging on my wall!) however, calculators came out, and I got an hp-35.  great calculator, and a huge difference from using a slide rule. in fact, guys would get together so that everyone could see how the calculator worked, and crank problems out as a group with the calculator accuracy!

fun times … with a couple of cold beers from jim’s.

Allen Montero ‘75

My office looks like a museum of old computing equipment, including slide rules.  I also have a deck of punch cards with the Michigan Tech seal in the middle of each card.  Some current students look at a slide rule and imagine it is a piece of drafting equipment.  During my junior year at Tech, the HP-35 pocket calculator became available, replacing the slide rule for those who could afford the $399 price tag.

I still have my slide rule, but don’t ask me how to use it…. Or to find it. I know it is in one of those boxes I have in my storage room. As for THE technology: the TI whatever that only added, subtracted, multiplied, divided and had a square root key for $160 brand new! So no, I did not have one. I did all my math by hand or slide rule from 73-77.

Anita Uhlir ‘77

I used my slide rule for my freshman and sophomore years.  The hp 35 scientific calculator came out during the summer between my sophomore and junior years.  The MTU faculty embraced the new technology so quickly; that, by the end of my junior fall quarter in ChE, the nature and amount of homework had changed where you had to have a scientific calculator to keep up!  An hp 35 was my only Christmas present that year and I was thrilled to get it! It cost about 70% as much as my car and it was a real sacrifice for my family.

When I started work in 1973 we made copies of drawings using a blueprint machine. I have a time stamped blue print drawing from 1921. This means technology did not advance for more than 50 years. It wasn’t until computers became affordable that we got CAD and better printing and copy machines.

We only had the slide rule for the first three years. There was an IBM 360, in the basement of Fisher, that read punch cards. During my Senior year, kids started getting the $400 HP-35. I was able to get a four function calculator from Montgomery Ward for $100.

Of course! I keep it mounted on my wall with a tag saying “Emergency Backup”. Engineers always should have a fall back solution.

Cutting edge technology? at the time was the slide rule.  We also had mechanical adding machines in the Civil Department.  Had my slide rule through senior year. Hand held calculators were just coming around.  I remember the Civil Dept raffling off a Hewlett Packard adding, subtracting, multiplying and dividing calculator in maybe my junior year(1971/2).  Retail cost $400.

Tom Permoda (Civil-1973)

I didn’t know that Tech has a memorabilia display in the Alumni House, but then I didn’t know about any Alumni House.

Attached is a photo of a wall hanging I have and wonder if the university would be interested in this one for the display. It would be donated if there is real interest. On the back it states it was made in Germany. It is mint condition. At auction today, with the right attendance, it might draw several dollars; for insurance purposes maybe in the tens of dollars. I can offer later details on how I came across it.

After receiving a BS from MCMT in Electrical Engineering in 1962,  I stayed on to receive an MS from MTU in Nuclear Engineering in 1963. That makes me somewhat special (Mr. Rodgers told me I was special) in that I have a degrees from MCMT and MTU.

In 1962 we were using book bags.  Their use made a good impression on me that first week at tech.  I thought that tech was a neat place – it didn’t matter how dorky they might look, the fact was they worked. I was certain they weren’t used at U of M or MSU but a tech we were there to learn engineering and what every might help to reach that goal was okay and their use didn’t need apology or explanation.

After my wife, Mary, and I got married on December 27, 1962 she then came to live with me in a second story apartment at 203 Portage St. Our landlord was, Hank Swank,  ran the laundry at the hospital.  During our summer there, Hank tore down a house on the NW corner of Portage and E Houghton to provide parking space for his tenants.  I worked with him on this project.  In the house we found the wall hanging which he gave to me.

I live in Washington State now but every summer I drive (only on the blue roads) to my cabin on Drummond Island.

-Thank you Alan for donating the wall hanging to Michigan Tech. We will display it proudly at the Alumni House. -SW

About the book bags, everyone had them when I arrived at Tech in the Fall of 1962. The 5th year seniors too and theirs were well worn. Thus I feel safe saying that they must have been in use since at least the late 50s. Considering the heavy books we had to carry, the freezing temps and the frequent falls on the ice and snow, it is hard to imagine not having one. [I didn’t mention having to carry a slide rule in them, because they were generally attached to your belt not carried in your book bag although I imagine some were.

Great newsletters!  I keep sharing them with my grandsons [13 and 15] who are considering Tech.

Great to see this note!  I acquired the first of several in 1977 when I arrived at Tech as an Instructor of Archaeology and Anthropology. They were sold in the Bookstore, manufactured by Duluth Tent and Awning, now Duluth Pack. There is a great history at the Duluth Pack website (https://www.duluthpack.com/history). I always thought that they were made as geological sample bags, and were certainly used for that purpose, but it appears that they were designed in 1912 as shot bags, for carrying shotgun shells. The bag I am carrying these days was also designed for that purpose, but is a little different in shape; they call it the Mini Haversack. After eight years, it is showing some wear. I have worn out two or three of the original Shell bags, carrying all sorts of tools and stuff into the field doing archaeology and traveling around the world: the Caribbean, the Arctic, Australia, Europe, China, Japan, and all over the US. They have done the job for me, even after wearing through on the corners from projecting edges of clipboards and such, and being patched by Mr. Johnson, former owner of the shoe repair shop under the parking deck in Houghton.

Yes, I still have my bookbag.

Your comments are a little conservative, as the famous green canvas bag was widely used before the 60s and 70s.

I came to Tech as a freshman in the fall of 1973 complete with a well used bag. It was my father’s that he used as a EE from 1949 to 1953. It served me well during that first year, after which I continued the tradition and purchased a new one. It saw continuous use until my graduation (CE) in 1977.

Today that bookbag still gets used. As a collector car and restoration hobbiest, I take it to swap meets and car shows often. It’s great for holding parts and literature.

Mark O. Lentz, P.E. ’77

I still have my old book bag. I converted it long ago to a fishing equipment bag, in which I carry an extra reel, fishing line, and assorted lure boxes. When I go brook trout fishing I put my fly lures and associated equipment in the book bag. When I go fly fishing, I switch out the fly gear for the spinning stuff in my vest. It is also used to augment and replenish my fishing vest. It also brings back memories.

I still have my book bag, acquired new from the Tech Bookstore in the fall of 1961.  I know they were common earlier; my cousin who attended Tech in the 1950s had one.

Jim Larson BSME ’65

Yes, I still have my Tech book bag. Used it in the 1960s. Everyone used book bags then.

Robert T Wicklund, BSME 1969

I think you will find that the Tech book bags were in use much earlier than the 70s. One of the first items I bought at the bookstore as a freshman in 1956 was a book bag. As I recall , most students had them. Like slide rules hanging from your belt, they were considered essential equipment. I left mine at home when I reported for active duty with The Corp Of Engineers after graduation and never saw it again as I spent 3 ½ years in France before returning home.

Matt Koski ’60

–

The bookbag was at Tech long before the ’70s. When I arrived in the fall of 1964, that was one of the first things I purchased at the book store. Everyone had one. I used to pack that thing so full I could hardly carry it but it saved me from having top make return trips to the dorm. These were the days before backpacks where the thing. And yes, I still have mine!

I still have my green Tech bag which I still use for hunting, fishing, etc. I bought it at the Union in 1963.

Saw the newsletter story about the “iconic” Tech bookbag.   Here is a picture of one I still have in my closet.  It was the second one I used at Tech (’69 to ’73) after I wore the first one out.  I agree with the “iconic” label.  After I graduated, as a ham radio enthusiast, I found it handy for carrying purchases while I walked around local “Hamfest” flea markets.  More than once, someone would stop me and ask if I had gone to Tech.

I have looked for a replacement bag, but all the ones available from Duluth Bags are a lot fancier and priced likewise.  I would think there would be an interest in that basic bag from Tech Memorabilia store.

Book bags go back at least to the 1950s. It was amazing what you could cram into them.  I remember students carrying them with a T-square sticking out.

In the 1970s I used two of them as saddle bags on my snowmobile.  Great for carrying a couple six packs!  I still have one that I use to carry tools around in.

Chuck Matrosic ’63

I no longer have my book bag, but I can tell you first hand that it was very common in the 1960 to 1964 period (and probably the remainder of the 60s), not just in the 70s and 80s.

Richard Beauregard ‘64

–

Those book bags were very popular in 1964 and 1965 when I was at Michigan Tech. I no longer have mine.

I assume that backpacks put an end to the Michigan Tech book bags – but have always wondered.

Yes I do still have my old “TOOT” Bag, but it finally died of old age and much use as a rock collecting bag both at Tech and after I graduated. Note: I still have not given the remains an appropriate burial because I just cannot seem to part with it.

I found it so good for rocks and light enough that I tried to purchase new ones but I believe they finally stopped making this type. Alas “The back pack” has taken over. However being a Tech engineering grad I made some modifications and found a local firm that used what was left of my “poor old bag” as a pattern and made me several new ones. I had to use white canvas rather than the original Tech green and the leather strap and closure was replaced with nylon webbing material. I also added a wider shoulder pad.

Boy I would have really loved that when I was going to Tech toting all those heavy text books.

Also as a note I am a collector of Copper Country and MTU memorabilia and have many items from the early days of MCM, MCMT as well as a rare sticker for: Michigan College of Science and Technology ( MCST )

That was not adopted on January 1, 1964 (by a quirk of the board) and became MTU shortly thereafter.

I looked for my 1959 book bag but apparently has been discarded. I remember a small hole burned by acid in chemistry lab. The only things I have left are my slide rule, diploma, and many many good memories. Who could forget 8 AM math class at -20 and 6 inches new snow.

I attended Tech from ‘67 to ‘71 and my green canvas book bag was almost a permanent fixture of mine. Living off campus, it was about the only good way to take a days worth of books with me, particularly when I lived in the Nutini cottage 6 miles out of Hancock. Alas, mine wore out with the canvas giving out shortly after graduation. The bag knew its service was done.

Dan Schmidt, Met Eng-1971

Those book bags go back into the 1960s.  I used my brother’s bag when I finished my last two years at Tech 1975-1977.  His was lighter green and well-worn.  He graduated from Tech in 1968.

Marietta Ehlers Johnson, BS in Biology, 1977

I still have my bookbag, however mine doesn’t look as good as Dave’s.  It has a few faded addresses written on it, barely can read Wadsworth Hall, 717 Ryan St and 202 Franklin St. A seam or two are coming apart, it’s faded and the leather has seen much better days.  I have almost tossed it out a few times, however it was with me through Doc Berry, Prof Tidwell, snowstorms and a few fender benders.  So it remains on a closet shelf next to my everyday duffle bags and the baseball caps I can’t seem to part with either.

Craig Harju ’73

I graduated in May 1959. Those book bags were everywhere. About 90% used them as I did so the history goes far back of the 70s or 80s

This type of bookbag was widely used on the Tech campus in the 1950s and 1960s accompanied by the big leather-cased slide rule !

The green book bag was quite prevalent when I was at Tech 1966-70.  And I still have mine.

Camiel Thorrez BSME 1970

I still have my book bag. And it was used in the late 50’s and early 60’s. I graduated in “61”. In fact, I have two of them. The one that served me at Tech was in pretty bad shape, so when we went up for a Winter Carnival a few years after I graduated, I bought a new one. I use it when I go out hunting for turkeys in the spring and deer in the fall. I also use it in the summer when we go to tractor shows to carry when browsing in the sales area to carry small stuff I just have to have. So it is still serving me well.

Andy Robinson ’61

Yes I still have my canvas bag.  It is worn but still worthy.  It carried all my books while at Tech and even served as my laptop case for awhile while I was consulting several years after graduation.

Oh yeah! I still have my Tech book bag which I used at Tech from 1961-65. Lots of good memories with it. I still use the bag regularly to carry mail in as our house is 300 yards from the mailbox.  I was fortunate to be at Tech when we won our first 2 NCAA hockey championships. Now that was fun!

Joe Mikols, BSME ‘65

I got mine in 1971 or 1972, since graduating it had been full of softballs and hardballs hanging in my garage. Not quite what was carried in it during my school years.

Mike Robinson- Forestry-1974

–

Yes!  Probably Circa 1973, the first, 1971 wore out. It is still in good shape and my wife uses it from time to time.

It held all that we needed. Today everyone has a backpack from age 6, the laptop, iPad, kindle, phone, chargers, calculators, water bottles,  etc.,  probably wouldn’t fit today and there is no padding.

It was a great thing. Everyone had one.

Don Beyer ’76

Book bags – remember them well – my shoulder remembers them too! Both my husband Tom’s and mine fell apart many years ago.  Even though they were built very rugged with heavy green denim type material, with a heavy leather strap, they didn’t last forever.  I went through 2 during my 4 years.

They were used way before the 70s.  I got my first one the Fall of 1967 and Tom got his the Fall of 1965.  I’m sure they were used in the early 60s if not before.

I think ours wore out faster because we used them as collection bags when we went agate picking!!

Gretchen Paupore ‘71

The MTU Bookbag is older that  you imply in your article!  There were plenty of well-worn book bags around campus when I arrived in 1958.  My guess is that they are a remnant of WWII, but I guess you will have to figure that out!

I used a bookbag like the one you are showing when I went to Tech in 1954-55.
