Can you confirm that all of the Dave Twyvers mentioned below are in fact the same guy who wrote the 3270 DSR that we both worked on?


From http://findarticles.com/p/articles/mi_hb270/is_2_21/ai_n28909265/pg_2/: "Ensemble Communications President and CEO Dave Twyver recognized CTC's innovation ..."

 After Helsinki, my jumping from Xerox to start 3Com was easy. Twyver, on the other hand, lingered at Nortel, eventually heading its wireless group, with 16,000 people and $2 billion in revenues.

Last September, 20 years later, Craig McCaw and Bill Gates convinced Twyver to jump. He finally left Nortel to become CEO of Teledesic (http://www.teledesic.com), which has 75 people and zero revenues. Teledesic is an Internet-in-the-sky start-up in Kirkland, Wash., that uses some of the Pentagon's more promising "Star Wars" technologies.

In March, the Federal Communications Commission licensed Teledesic's constellation of low-earth-orbiting communication satellites. Twyver is now planning to launch 24 pole-orbiting satellite rings, 15 degrees apart, 12 satellites each, about 800 miles up.

From http://www.mail-archive.com/freebsd-hackers@freebsd.org/msg53683.html: "And Dave Twyver at University of British Columbia was the guy who wrote the 3270 DSR (Device Support Routine), ...".

Dave Twyver Dave arrived at UBC in the summer of 1968 just as his past 7044 expertise was about to be obsoleted by the new 360/67. His first assignment was to write a DSR for the 2260 Display Stations to make them emulate cardpunch machines (which seemed to him like a really dumb idea). After intense study of Mike's 2741 DSR (TSFO) and after weeks mastering the subtleties of device interrupts, re-entrant code and page faults due to misuse of the TRT instruction, he produced a DSR more befitting a revolutionary interactive time sharing system like MTS. When the improved 3270 display stations came along a couple of years later, all of the card punch heritage was able to be expunged. Major portions of this 3270 DSR code were subsequently pirated by frustrated users of the TSS and VM operating systems for the 360/67 and its successors. Some of Dave's other contributions to MTS included a DSR for the Adage Graphics computer, an emulator for the DEC PDP-8 and a DSR to interface PDP-8s to MTS. He also adapted and integrated an interpreter for the APL language into MTS, which was a deciding factor in convincing the University of Alberta to adopt MTS (at least for a while...) Dave spent his last couple of years at UBC developing a campus computer network. He left in 1974 to join Northern Telecom (now Nortel) where he spent 22 years working in its Networking and Wireless businesses around the world. Then in 2002, after several years investing in and managing (with very mixed results!) start-up companies in the satellite and terrestrial broadband wireless access areas, Dave retired to Vancouver Island within sight of UBC (on a clear day) across the Strait of Georgia.

Obituary for James O. Henriksen 

July 10, 1945 - April 6, 2019

James O. Henriksen, 73, passed away on Saturday, April 6, at home in Lewes, DE, after a hard fought battle with Idiopathic Pulmonary Fibrosis. Founder and CEO of Wolverine Software Corporation, Jim and his wife, Judy, moved from Alexandria, VA to Lewes in 2011. He anticipated retiring with the move, but never could give up his passion for contributing to the evolving field of computer simulation.

Jim was born in Muskegon, MI, the youngest of three children to parents Anna and Henry Henriksen. He attended public schools in Muskegon and spent summers working in his father's auto glass business, learning mechanical and interpersonal skills that served him the rest of his life.

Jim graduated from the University of Michigan with a B.S. Degree in 1967. Having already developed a love of percussion while in high school, he joined the Michigan Marching Band and spoke proudly of Michigan's football success that took him to the 1965 Rose Bowl in Pasadena, CA. He remained an avid college football fan forever.

Jim's University of Michigan graduate MBA courses were interrupted in the Spring of 1968 when he was drafted into the US Army. Thinking he was headed to the jungles of Vietnam he, instead, was diverted by special Pentagon order to work with the Safeguard Antiballistic Missile Program. He was given the highest level top secret security clearance allowing work with Critical Nuclear Weapons Design Information. Spending two years in the DC area, Jim grew to love Virginia, happy to be away from the cold and grey Ann Arbor winters. His military service introduced him to people and situations that influenced greatly his career decisions in the months following his discharge in 1970.

In spite of his dislike of the long Ann Arbor winters, Jim returned to Michigan after being invited to work at the Michigan Computing Center. He remained there for four years working as a research and teaching assistant, all the while building his interest in, and ideas for, problem solving using computer simulation software.

In 1974 Jim was happy to return to the DC area, having been offered a job with the large defense contractor, CACI. Within a year, however, he left CACI and founded Wolverine Software Corporation in order to pursue his goal of building a “better mousetrap” in the form of a more powerful simulation program than that previously introduced by IBM. His work in taking on the giant was successful and formed the solid foundation for Jim's future programs including simulation animation. Jim's work has remained prominent in the field of computer simulation for over four decades.

Jim taught graduate level courses for five years as an adjunct professor of computer science for Virginia Tech Northern Virginia Graduate Center. He has given numerous presentations on simulation at conferences, corporations, government organizations, and other universities around the world. His sense of humor was legendary, even when speaking his 2nd language, German. He was fond of saying, “If you are not part of the solution, you are part of the problem.” He had a clear vision of his goals and ideals, always raising the bar by seeking perfection.

Over the course of his career, Jim authored over 50 books and articles and was working currently on what would have been his last work. He was indebted to Jim Wilson for helping him so much in recent months as his health began to fail. Jim also would want to thank Bob Sargent for his on-going support when he most needed it, and Tom Schriber for his advice and friendship over more than half a century.

Of the many awards Jim received over his lifetime, he felt honored to have been selected Titan of the Year and Keynote Speaker for the Winter Simulation Conference held in Monterey, CA in 2006. In 2013, Jim was video interviewed as a Simulation Pioneer for the Computer Simulation Archive located at North Carolina State University Libraries. And, in December 2018, in Gothenburg, Sweden, Jim was given the prestigeous Lifetime Professional Achievement Award by INFORMS, premier international computer society with over 10,000 members.

Jim also enjoyed a variety of activities outside his professional endeavors. He loved keeping fit and worked out regularly at a gym. He enjoyed competition on all levels and played a fierce game of racquetball. In earlier years he participated in sailboat races on the Chesapeake Bay. He was a hiker and a bicyclist who loved exploring new parks and trails. He loved his dogs, of which there were many over the years. Jim never gave up his love of classical music and volunteered in several concert bands, including the Virginia Grand Military Band, commuting back to Alexandria to play Timpani and other percussion at the Schlesinger Concert Hall and Arts Center.

Jim developed lasting professional relationships and loyal friendships all over the world. Known by all who met him for his brilliance, patience and kindness, Jim was a special man who made a difference in the world, his community, and in the individual lives of many.

Survivors include his wife, Judy (Merrill) Henriksen; his brother Richard (Rosemary) Henriksen of Traverse City, MI; brother in law, John Seelman of North Muskegon, MI; many nephews; and goddaughter niece, Christine (Robert) Koman of North Muskegon. His sister, Mary Ann Seelman predeceased him in 2013.

A private service for Jim will be held in June in Michigan. At a later date, a few close friends will gather in Alexandria to share a meal and memories.

Suggestions for donations in Jim's memory are the Lewes Fire Department, 347 E. Savannah Road, Lewes, DE 19958, Faithful Friends, Inc., 12 Germay Drive, Wilmington, DE 19804, or a charity of your choice.

    I met Jim when he became my boss at the University of Michigan Computing Center --- he was in charge of the Computing Center counsellors when I became a Computing Center counsellor. His wit and common sense were always much appreciated. Later, he arranged for an interview for me at CACI which led to my first job in the DC area ( but like Jim, I left CACI within a year for another opportunity). I remember his love of music, and a well-spun story with a good punch-line, and trying to figure out how something really works, and always, the University of Michigan. And I well remember how happy Jim was when he met Judy in their townhouse community, and how their whole happy story together evolved. With deepest condolences to Judy and Jim's family, Jurate Maciunas Landwehr

    Jim was a great friend and a real inspiration to me. Lots of us remember him as the coach of the Computing Center softball teams -- both men and coed. We had some really memorable times. I called him coach for the next 40 years, and only partly because of the softball team. I overlapped Jim in the Marching Band for his last 2 years (my first 2) and we talked band stories ever since. Most impactful to me, though, was his creation of GPSS/H, his compiler for GPSS. It ran 10 times faster than IBM's GPSS, and was the proof of concept I used when making a compiler for Verilog, another simulation language. When you know the idea is sound, it makes development a whole lot easier. Jim did it first. He was one of the (quiet) giants of the UM Computing Center -- a key contributor to making it the great place it was.

    Dinner parties, wine, laughter of Judy and my old school day tales from elementary and high school. Loved when Jim would hold us spell bound with a well delivered joke of his. I always had a joke for him but not as well told as his. We both had strong Scandinavian ancestry. His Norwegian mine Swedish. We kidded each other about this. George and I will miss you Jim and we will always remember our fun times.

    With Jim I lose not only a brilliant business partner and an extraordinary customer-oriented software vendor. I lose a true friend. Without Jim, I would not be where I am today. It was Jim who introduced me to Gordon, who eventually hired me nearly 17 years ago.

    Jim was that kind of guy who could "talk" to computers and make them do what HE wanted them to do. In nearly 2 decades I have been working with Jim, I never ran into a problem with SLX or Proof which he was not capable of fixing in the very same day.

    Jim was not only a phenomenal programmer, he had also a great sense of humour. A couple of anecdotes from his presentations: in one, still using transparency sheets with an overhead projector, he had drawn a hand on the side of the sheet. We all thought it was his own hand, holding the sheet on the side. When he walked away from the sheet and the "hand" stayed, most of the people in the audience looked puzzled (myselft included).

    In another presentation, years later, he created an animation and the word SLX turned into the word SEX for a very short time every so many seconds. Again, most people in the audience thought they were having hallucinations.

    I'd like to close this short memory with one of Jim's famous principles (from his Titans Speech "Taming the Complexity Dragon" at WSC): according to Jim, a good software needs to satisfy the "Principle of Least Astonishment", i.e. be intuitive and do not astonish the customer. An example of a violation of such principle? Going to START when you want to switch OFF a computer.

    Godspeed Jim, I will miss you. Judy, a big big hug to you.

    I’ll never forget when Jim & Judy came all the way to Illinois to attend the funeral of my first wife, and then came over to my house to meet my relatives. Jim rendered my mother-in-law speechless when he said he learned how to swim when his parents threw him in the water. When my mother-in-law exclaimed “How terrible...” Jim replied in classic JOH humor “it wasn’t so bad...once I got out the bag I was in, the rest was easy.” All who knew Jim has a JOH story and all will miss him.

I just want to let you know that Jim passed away at home early Sat morning,  result of his Idiopathic Pulmonary Fibrosis.  His health had declined quite a bit from when you visited and he no longer could walk or do anything on his computers.  He was so miserable and struggled to take every breath.  I thought we had a couple more months, but it was not to be.

There will be no public memorial event in Lewes, just a family service in Michigan in June.  Then, later in the summer, I plan to do something in Alexandria in a park or garden in Alexandria, again, not an event, just a very few close friends.

I am OK, but in shock still, and have so many loose ends having to do with Wolverine, etc.  Jim thought he had a little more time, too.

Hope all is well with you both and that Carl's mother is doing OK.

I apologize for the email, but wanted to give you the news from me before you heard it from others.  Feel free to pass the word along to those you know who might be interested.

So glad you got to visit us in Lewes when you did.

Obituary for Frank Westervelt

Westervelt, Franklin 3/26/1930 - 7/29/2015 Ann Arbor Dr. Franklin Herbert Westervelt passed away on July 29, 2015. He died peacefully at his Ann Arbor home, attended by his daughter, Wendy, his caregiver. He was born in Benton Harbor, MI, on March 26, 1930, the son of Herbert Oleander Westervelt and Dorothy Ulbright Westervelt. Franklin received degrees in Mathematics, Mechanical and Electrical Engineering from the College of Engineering at the University of Michigan. He attained his PhD in 1961 and was an Associate Director of the U of M Computing Center. He was a professor of Electrical and Computer Engineering at Wayne State University, where he served as Director of the Computing Center and Chairman of the ECE department. He was part of the team that developed the MERIT network, linking computers at U of M, MSU and Wayne State University, an early "internet" between the three state universities. Franklin was a wonderful husband and father. He was a master of home projects from decks and boathouse doors to swing-and-slide sets and sandboxes. He also supported strongly the family wildlife sanctuaries in both the Ann Arbor and Traverse City areas, and devoted many weekend hours improving and enjoying them. Franklin is survived by his son and daughter-in-law, Andy and Linda (McCarren); their four children Renee, Eric, Laura and Peter; his daughter, Wendy; his nephew and his wife James and Aida (Datuon) Ednie; and his faithful Lhasa Apso, Merlin. Franklin was preceded in death by his loving and beloved wife of 65 years, Louise (Andrews) Westervelt; his sister-in-law and brother-in-law Frances (Andrews) and William Ednie, and one niece Linda Ednie.

Frank came to Wayne State University in 1970 to become director of our Computing Center. It was great to have a man of his stature come to our center. He brought the MTS computer operating system to Wayne, and I enjoyed working for him and with him. He had an open-door policy of directing the Computing Center, and I often walked in to discuss an issue with him. My sympathies go to his family and friends.

posted May 5, 2016, 7:40 PM by Jeff Ogden   [ updated Dec 12, 2020, 3:49 AM ]

Bob Graham died on January 2, 2020.

Wikipedia article: Robert M. Graham

He was a significant contributor to the deign and implementation of the Multics time-sharing system and the MAD compiler; SIGPLAN chairman; CACM department editor; National ACM Lecturer; University of Massachusetts Computer Science Department chairman; and author of the textbook, Principles of Systems Programming.

In Memoriam: Professor Emeritus Robert M. Graham (1929–2020)

Published on January 22, 2020 by the College of Information and Computer Sciences, University of Massachusetts Amherst.

Robert M. Graham, 90, emeritus professor of computer science, died Thursday, January 2, 2020.

Graham came to UMass Amherst in 1975 as chair of the computer science department, serving in that role until 1981—during which time he oversaw the development of the undergraduate major in computer science, adding to the existing master’s and doctoral programs—and then as a professor until his retirement in 1996. He continued to teach one course, COMPSCI 201, each semester until 2003. Graham’s research at UMass Amherst focused on software development environments. 

"Bob Graham greatly influenced the shape of our department, bringing important background from the early days of computing research, including writing compilers for the IBM 650 and 709 series and working as a key member of the team that developed the landmark Multics operating system at MIT,” said Eliot Moss, professor and graduate program director at CICS. “While firsthand memories of Bob will fade over time, his early guidance of the department will continue to have an enduring impact. Thank you, Bob!"

Born in Michigan in 1929, at the beginning of the Great Depression, Graham spent his early years on his grandfather’s small farm and moved to a small town at the age of six when his parents found employment. After graduating high school, he studied mathematics at the University of Michigan until he was drafted into the US Army during the Korean War. It was during his deployment to Tokyo, as a clerk with the Army Security Agency, that Graham first became interested in computers. 

Graham received both a bachelor’s and a master’s in computer science from the University of Michigan and went on to hold faculty positions at the Massachusetts Institute of Technology, University of California Berkeley, and The City College of The City University of New York before joining UMass Amherst. He helped to design or implement nearly a dozen major pieces of software, including the MAD compiler, a COBOL compiler for a minicomputer, the Multics operating system, and an operating system for the IBM 709/7090.

He served as chair of ACM SIGPLAN, a member of the Computer Science Board, and associate editor of the Communications of the ACM. He was also an ACM National Lecturer.

Visiting hours to pay respects will be available on Friday, January 31 from 5–7 pm at Douglass Funeral Service, 87 North Pleasant St, Amherst MA 01002. There are plans for a larger memorial service on campus in late spring or early summer. Details will be added as they become available.

I was born in Michigan at the beginning of the Great Depression (1929). My father, like so many others, was unemployed. Fortunately, we were able to live with my grandfather (my mother's father) on his farm in central Michigan. Many of these small farms were nearly self-sufficient, so we did not suffer. My earliest recollections are of life on a farm, the most vivid being the rooster that rushed at me whenever I went into the barnyard. My mother, also unemployed, taught me to read. When I was six my father got a job in a near-by town. We moved there and I entered school in the first grade, while my mother resumed teaching high school mathematics. Growing up in a small mid-western town was mostly uneventful. Later fond memories are of trips to Kincardine, Bruce County, Ontario, Canada where my father was born. His father emigrated from Scotland, as did many of the other residents of Bruce Country. We would visit Kincardine in the summer during their Highland Games. As a young boy of Scottish descent, the games were very exciting (I am still stirred by the sound of bagpipes).

After high school I studied mathematics at the University of Michigan until drafted into the US Army near the end of the Korean action. At the completion of my training I was sent to Tokyo, Japan as a clerk in the Far East headquarters of the Army Security Agency. While there I became interested in computers. After being discharged, I returned to the University of Michigan where I finished my undergraduate and graduate degrees. In my first year I took the only computer courses offered by the University, a total of two -- "Introduction to Programming" and "Numerical Analysis". With this background I obtained a graduate assistantship in the University's newly established academic computing center. During my tenure with the computing center, I co-authored two compilers (GAT for the IBM 650 and MAD for the IBM 704/709/7090), implemented a concurrent IO system for the IBM 709/7090, and wrote numerous other programs.

In 1963 I moved to MIT to participate in the development of MULTICS, their pioneering time-sharing system. This was a major project that took about seven years from the initial planning until the system was in daily use by a large community of users. I was one of the principle designers, with particular responsibility for protection, dynamic linking, and other key system kernel areas.

Following MIT, I spent two years at the University of California at Berkeley and three years at City College of New York. In 1975 I moved to the University of Massachusetts at Amherst for a five year stint as Chairman of the Computer Science Department. After that I continued as an "ordinary" faculty member in the Computer Science Department. I officially retired in 1996 but continued to teach one course each semester until the end of 2003. I now devote my time to writing another book, consulting, production of Gilbert and Sullivan operettas, and my home town's conservation commission.

Plugging St Andrews In

Wednesday 30 September 2015


Marking 50 years since the first computer was brought into service by the University of St Andrews in the town itself, a small exhibition charting the changes in this now ubiquitous technology will open at the Byre Theatre on Thursday 1 October.

The first computer – an IBM 1620 Model II – was the largest system of its kind in Europe and it occupied an entire air-conditioned room within the University’s observatory. Valued at £135,000 in 1965 but purchased for £60,000, it cost around the same as a small housing estate at the time and was the result of more than a year of negotiations and planning.

The enormous machine was run around the clock, managed by the Department of Astronomy and trained operators.

While the capacity of the IBM 1620 is minute by modern standards, the computer was advanced for the time and played an important role in the development of computing in St Andrews.

Records from the time show that the computer was in use over 400 hours per month. Courses were held on programming and seminars were given by University staff who had made use of results from the computer. It was able to churn through extensive calculations and was most in demand by staff and researchers studying astronomy, applied mathematics, botany, chemistry, physics and theoretical physics.

Peter Adamson, retired Computing Officer from IT Services at the University of St Andrews, has worked with Roger Stapleton, Honorary Scientific Officer from the School of Physics and Astronomy, to gather together items for display.


These include elements from the first computer and its early successors like the BBC Micro and Commodore PET, along with documents – such as the 1961 letter from the late Professor Douglas Walter Noble Stibbs to the then Principal, Sir Thomas Malcolm Knox, putting forward the case for purchasing the 1620.

An array of objects and images from the 60s and early 70s show what life was like in what was then called the Computing Laboratory, including heavy hand-cranked calculators, a large steel printer roller covered in embossed symbols and lettering, and early punched cards, which served to input programs or data into the computer.

Mr Adamson said: “In 1965 the first computer service within St Andrews revolutionised our work. The equipment required careful programming and weekly engineering maintenance but we were now able to process enormous amounts of data locally instead of taking it elsewhere.

“I have fond memories of working with these early computers, and of course I enjoyed it when enterprising users made the IBM 1620 graph-plotter hum Christmas carols, or created a 3D noughts and crosses game. Due to a bug, the computer always won!”

Swift advances in technology and increasing workload meant that a replacement computer was installed in 1969. This IBM 360/44 was specially tailored for scientific use. It enabled computer programs to run 60 times faster than the 1620 model, and it had a central processor with a respectable 128K bytes of memory – dwarfed by today’s smart phones.

The First Computers in St Andrews will run at the Byre Theatre in St Andrews from 1 to 31 October, opening to the public with a free event on 1 October at 6.30pm and offering exhibition-goers the opportunity to see the exhibition first and meet Peter Adamson and Roger Stapleton.

Eric M. Aupperle, President Emeritus of the Merit Network, passed away on 30 April 2015 at his home in Ann Arbor.

See the People section of this web site for a short bio sketch for Eric.

I have some sad news to pass along.  Janice Short called me a bit ago to say that Eric Aupperle had died. She learned about it from the folks at Merit and they learned it earlier today. I don't have any more details other than he was found in his home and may have died several days ago. Eric's death follows the death of his wife, Nancy, not quite two months ago. Eric had just turned 80.

When I first came to the Computing Center, Aaron and Bernie sent me over
to have a chat with Eric. We had a great conversation that I can still
remember. When one of the committees were formed to plan the wiring
of the campus, I found out Eric asked Bernie/Aaron to put me on the
committee. I learned a tremendous amount from that experience and
met many of the to: actors on this message in that way. I never had much
personal contact with Eric and didn't know him well but he is one of my
"white hats" and a straight shooter. Merit was a great contribution to
the history of computing and the computing profession........

Yes, he certainly was a straight shooter as you said, Dave. I was saying to Liz
today that I don't think I ever knew anyone who was so unflappable -- he had a
very steady hand on the tiller. If he was ever rattled, it was hard to tell. He took
on responsibility in a serious way and worked tirelessly, generally without a lot
fanfare, to pull off some major accomplishments. A great model and mentor for
many of us.

It certainly is sad to learn of Eric's passing.  Memories of his smile, his laugh, his always warm, friendly, and thoughtful demeanor -- such memories easily come to mind.

One of many impressive things about Eric was how he brought together such talented people, and how good he was at nurturing and empowering them.  I can remember times when various of us, myself or others, would wonder why Eric would not just fix some work issue -- but now looking back with the perspective of time, it is easy to see that he helped us all accomplish more and become better ourselves, both as individuals and in the group's efforts, because of the kind of leader he was.  He was a natural leader. 

At some point, maybe in the late 1990's, I learned he did not trust ATM machines and had never used one.  I can only laugh thinking about all the incongruities of that.

Among my strongest memories of Eric and Nancy together was their enthusiasm for ski trips out west.  One of many great shared pleasures; I have to believe he was missing her a great deal.

Eric was a person who had the right talent, at the right time, in the right place, to make a huge difference.  At least a few of us know that and can honor him for it.

Curious, the seemingly insignificant things that one remembers, that color one’s lasting impressions of someone.

I didn’t work for Eric, but I interacted with him professionally on a number of occasions.

The thing that I will always remember about Eric is that whenever I returned a call from him, he would start out be saying, “Thanks for returning my call”, as if I were doing something special by returning his call.

This initial greeting had a very positive personal effect on me during the current (and any subsequent) phone conversations. First, because I hadn’t really done anything special (yet), I was predisposed to being receptive and helpful regarding whatever it was he might want to discuss. Second, I had an innate sense that if there was ever a time when I might want to discuss something with him, I felt that he would be very responsive and would do his best to be helpful as well.

Just a simply way to start out a phone conversation, yet extremely effective in communicating the message that he considered me a valued participant in discussing the subject at hand, and certainly guaranteeing that any future conversations between us would be useful and productive as well .

In retrospect, it’s not surprising to me that he was able to accomplish so much, working with so many people, on so many projects at Merit over the years.

His communication style encouraged you to be responsive and helpful, and you full well knew, flipping roles, he would do likewise.

Eric's obituary from M-Live:

Aupperle, Eric 4/14/1935 - 4/30/2015 Ann Arbor Age 80, passed away April 30, 2015. Eric was born April 14, 1935 in Batavia, New York to Max Karl Aupperle and Hedwig Elise Helen Haas. He moved to Ann Arbor in 1937 and graduated from Ann Arbor High School in 1953. He earned a BSE degree in both Electrical Engineering and Mathematics from the University of Michigan in 1957 and an MSE in Nuclear Engineering from U of M in 1958. He married his late wife, Nancy of 56 years, on June 21, 1958 in Dearborn, Michigan. Eric worked at the University of Michigan his entire career beginning as a research scientist in 1957 at the Cooley Electronics Laboratory. He spent most of his time at Michigan at Merit Computer Network where he retired in 2001 as President of Merit. He was also a lecturer for the University's Department of Electrical Engineering and Computer Science for 40 years. In his off time, Eric enjoyed traveling, spending time with his family and relaxing at the family cottage. Eric is survived by his children Bryan (Carol) Aupperle of Carey, NC, his daughter Lisa (Alexander) Hudy of Livonia, MI and his grandchildren Matthew, Daniel and Nicole. He is also survived by his sisters Charlotte (Douglas) McGregor of Cleveland, OH and Gertrude (Irving) Salmeen of Ann Arbor. There will be a private interment. A Memorial Celebration of both Eric and Nancy's lives will be held on Saturday, May 9, 2015 from 2-4 pm at Nie Family Funeral Home, 2400 Carpenter Rd, Ann Arbor. In lieu of flowers, the family suggests donations be made in memory of Eric Aupperle to the University of Michigan Electrical and Computer Engineering Fund (fund number 313472, U of M EECS Dept, 1301 Beal Avenue, Ann Arbor, MI 48109-2122), which supports student research, guest instructors and state-of-the-art equipment purchases.


A memorial to Eric from U-M's Electrical Engineering and Computer Science department:

Eric Max Aupperle (BSE EE and Math '57; MSE NERS '58; Instm.E. '64), renowned president of Merit Network and Research Scientist Emeritus, passed away Thursday, April 30, 2015, at the age of 80.

It is not often that an individual’s memorial tribute reflects a life lived in the heart of a major technological revolution. As director and president of a computer research network that played a contributing role in the development of the Internet, Eric Aupperle lived such a life.

Mr. Aupperle was a true Michigan man, devoting his career to the University of Michigan and to the State of Michigan in his role as director and later president of Merit Network. Throughout his career at Merit, Eric was an employee of the University of Michigan, serving for a time as Associate Director for Communications (1981-1989) and Interim Director of Information Technology Division Network Systems (1990-1992).

After receiving his bachelor's degrees in electrical engineering and mathematics in 1957, Mr. Aupperle was hired as a researcher of electronic devices at the U-M Cooley Electronics Laboratory. He was a lecturer in the Department of Electrical and Computer Engineering from 1963-2002, teaching digital circuits and other circuits and computer-related courses. By the mid 1960's, Eric was programming assembly language into the earliest version of mini-computers in the university’s Computer Electronics Lab.[1]

In the fall of 1969, Eric was hired as the first employee of Merit Network by the director, Prof. Bertram Herzog. His job was to implement a computer network that linked the University of Michigan, Michigan State University, and Wayne State University. Recalling the early years in a later interview, Eric said they had to build the technology, called communications computers (essentially routers by today’s terminology). Only ARPA was doing something similar at that time. [2]

"It was clear that we needed someone who had electrical engineering, circuit design capabilities," Herzog says today of his choice of Aupperle. "There was a lot of innovative stuff to be done." [3]

In 1973, the network was formally dedicafted, and for the first time a researcher at Michigan, for example, was able to run a program at Michigan State or Wayne State. A year later Eric was appointed director of Merit, and he would serve as Merit’s first president from 1988 to 2001.

Aupperle and BraunIn 1976, Merit interconnected with Telenet, a spin-off of ARPANET, which ultimately connected Merit users with the world. In 1983, Hans-Werner Braun was brought in from Germany to interconnect Merit's network with ARPANET itself. Once completed - Merit became the first network to support both a connection-based protocol and the connectionless TCP/IP suite. [4]

The next major milestone in Eric’s career occurred after the National Science Foundation (NSF) established NSFNET in 1985 with the goal of networking five new recently-funded supercomputing centers. Within just a year, network traffic far exceeded capacity, and NSF put out a bid to upgrade NSFNET to meet the demand.

Merit Network, which by this time had grown to include eight universities, was selected as lead organization of this upgraded NSFNET, a consortium that included IBM, MCI, and the State of Michigan. Eric would later write, “Almost overnight Merit’s role of providing networking services to our member universities and a handful of other Michigan-based organizations was extended to include an extremely significant, highly visible national networking function.” [5]

As President of Merit, Eric was called on many times to talk about NSFNET and the rise of networked computing.  In a 1985 article printed in IEEE Spectrum, he said, “The communications and computer industries evolved independently, but they have blended inexorably, both technically and, more recently, organizationally.”

By 1991, discussions of who owned the Internet, which itself was an object of some confusion, was a hot topic of conversation. In the article, Just Who Owns the Internet?,  Eric was quoted as saying, “When one talks of the Internet, you have to envision a large number of networks, some of which are major backbones like the NSF Net. Others are statewide or regional networks, others are networks within colleges or research educations or labs. What counts as ownership? ... The desired outcome is access as open as it is today, in terms of the educational and research community, and also for commercial users.” [6]

Dan Atkins III, Professor of Information and Electrical Engineering and Computer Science, former Dean of the College of Engineering and the School of Information, and inaugural Director of the Office of Cyberinfrastructure at NSF, confirmed the importance of Eric's leadership and Merit's role in shaping the Internet:

"Eric Aupperle was a pioneer contributor to the rapid emergence of the Internet as we now know it. Pre-internet he headed the development of MERIT, one of the very first regional computer networks. MERIT created the capacity for the University of Michigan to win the operational leadership of the NSFNet, the project that led to rapid adoption of the TCP/IP standards of the original ARPA Net to all of higher education. This rapid growth launched TCP/IP as the open defacto standard for all of the Internet and thus dampened the attempts by commercial parties to establish proprietary networks. The internet may well be very different today were it not for the talented leadership of Eric Aupperle and colleagues at the University of Michigan."

In the early 1990’s, Merit successfully worked to provide network access to K-12 schools throughout Michigan. Merit also helped develop the University of Michigan’s GoMLink, the first virtual library on the Internet. In 1994, Merit became involved with the North American Network Operators’ Group (NANOG), the professional association for Internet engineering and architecture. Merit coordinated and managed the activities of NANOG until 2010.

NSFNET funding ended in 1995. Eric said the $50M spent by the government resulted in “a great return on investment.”

Doug Van Houweling, Professor of Information, took over as president of Merit when Eric stepped down. Prof. Van Houweling served a Chairman of the Board at Merit during NSFnet, was Chief Executive Officer of Internet2 between 1997-2010, and is a member of the Internet Hall of Fame. He stated:

"Eric Aupperle led Michigan's higher education network, Merit, through three decades of innovation. He had a unique talent for attracting gifted colleagues and welding their sometimes disparate visions into action that kept Merit at the forefront of network technology and applications. His crowning achievement was leadership of the NSFNET project which demonstrated that Internet technology could serve millions of users and led to today's Internet. Eric's leadership changed the world."

Eric remained committed to Merit’s purpose as being “Michigan’s premiere network service provider for our educational and research communities.”  Merit is still an active non-profit organization, providing high-performance networking and services to the research and education communities in Michigan as well as across the U.S.

In recognition of his leadership at Merit and resulting contributions to the history of networked computing, especially for the research and educational community, Mr. Aupperle was awarded the highest alumni honor by the College of Engineering, the Alumni Medal, in 2003. He received the IEEE Third Millenium Medal in 2000. Eric also served as a board member of the EECS Alumni Society from 2004-07.

"The department is honored to have counted Mr. Eric Aupperle as a friend and colleague," said Khalil Najafi, Schlumberger Professor of Engineering and Chair of Electrical and Computer Engineering. "We salute his extraordinary accomplishments as leader of Merit Network, and offer our sincere condolences to his entire family."

Vern Dettwiler

From Facebook: https://www.facebook.com/RASayle/posts/10204032541997067?pnref=story

I was fortunate to be hired by the UBC Computing Centre in 1968. I was also fortunate to last 34 years there.

Those were heady times in so many ways. Computing technology was zooming ahead, lots of new staff and staff turnovers and the music was great.

Our Director was James M Kennedy and he passed away in 2004. Then the Associate Director was Al Fowler and he passed away in 1998. Back then when I started, the person in charge of Special Projects was a very brilliant electrical engineer named Vern Dettwiler. Vern could built anything electronic and was lured away from UBC by Dr John Macdonald to form Macdonald, Dettwiler and Associates. It was soon to become Canada's greatest aerospace industry.

I remember being shocked when he left UBC, feeling he left us with a huge void. But, as I said, those were heady times and we soon replaced him with other incredibly gifted people.

Time flew and I wasn't one of the people that Vern kept in touch with. I heard he had retired back to Switzerland. A few hours back, I was googling something or someone and put in Vern's name. I was shocked to see his obituary at the top of the list. Shocked that he passed away 18 months ago and there was no mention in either the local or national newspapers.

I just remembered what I was looking for. I discovered there was a Dettwiler Pavilion in the UBC Hospital buildings. I was looking to see if Vern was involved and how much was involved... Don't remember any mention of that either in the papers.

Lots of Vern stories out there, I'm sure.


A memorial service for Werner is to be held at the Eichfeld Cemetery in Steffisburg (Eichfeldstrasse 24), at 14 hrs on Tuesday 1 October.


  • Dennis O'Reilly Wow Ralph. Thanks for posting this. I remember working with Vern in the early years.
  • Ralph Austin Sayle Before they got MTS, Vern agreed to build an device to interface Teletype type devices for MTS. I heard tales that he figured out the IBM Channels by scoping them (reverse engineering) and then he and the shop built the interface.

    Peter M was telling
    me recently that the device would freeze the IBM channel which could only be reset by a re-IPL.

    Also before my time, the Systems Group (I think) roughed out the design for a software package to replace the hardware multiplexor that had never worked.

    That's about when I came along to pick up the implementation started by Don McWilliam and then you picked it up...

    By the time I joined the Communications Group in 1974, Vern had departed for other greener pastures.
  • Ralph Austin Sayle Something else I figured out from reading and googling about the Computing Centre's history... before i was hired.

    Vern was the machine room supervisor for the IBM 7044 and even built special hardware to make the machine more productive in the mid to
    late 1960s.

    Originally printing was done on-line as a job progressed. I remember one researcher telling me that his very long jobs occasionally ran out of time because it had to wait for the printer to be readied. His solution was to write out a few dozen lines of asterisks on the console "to wake up the computer operator".

    Vern changed the process so a CDC 8092 was used to create input (the waiting card decks were read onto a tape) tapes and also to drive the printer from the output spool tape created on the 7044. I remember those days quite well... I think there were even spool tapes to drive the plotter. to add a forgotten name, Norm Finlayson did Vern's programming. Norm was there when I started but he left for medicine.

    The spooling process was quite reliable but occasionally the 8092 hung up. the "solution" was to knee one of the panels. It worked. Hmm, I was never curious then why it worked or what was behind the panel.
  • Karl Acton Ah, Fortran IV and punched cards, a form of Hell.
  • Ralph Austin Sayle Vern in one of those old IBM posed photos from the UBC archives. I forgot about the bow ties.
