 MTS Workshop Proceedings

Don Boettner recently made his collection of proceedings from the 19 workshops held from 1974 to 1994 available for scanning. So far we've been able to scan the table of contents materials (schedules, list of papers, list of attendees) from all of the workshops. They are available in the "Documents section" of the MTS Archive site (this site). We hope to get the full proceedings scanned as well. Once that is done, the physical paper copies are destined for the U-M's Bentley Historical Library. We would like to thank Don for saving the proceedings and being willing to make them available.

These images are from the front and back covers of the 1975 MTS Development Workshop Proceedings held at the University of Alberta (UQV). If you know or think you know who this is, please send a note to mts-comments@umich.edu.

Update 16 June 2014
Bob Engley identified this as Lloyd White and Rolly Noel and Vic Yanda confirm that Lloyd was a staff member in UQV's publishing group. He later moved to the applications group when it was created.

Ron Srodawa
Ron Srodawa passed away on January 1, 2014

Ron died of complications of Alzheimer's disease. Ron's obituary is available here.

Ron earned his PhD in Computer and Communications Sciences from the University of Michigan in 1972. He was involved in the early days of the development of the Michigan Terminal System. He wrote the MTS loader (UMLOAD), which Mike Alexander remembers as remarkable because it (i) fit in one page of memory and (ii) was location independent, you could put it anywhere and call it and it would work, there was nothing in it that had to be relocated when it was moved to a new location. He also worked on the development of the MAD/I compiler as part of the ARPA funded CONCOMP project at U-M.

He was appointed an instructor and Professor at Wayne State and Oakland Universities. His professional life included academic research, teaching bachelor, and doctoral students and consulting for Ford Motor Company.

A video oral history interview with Jim Henriksen

Jim Henriksen worked at the U-M Computing Center in the late 1960s and early to middle 1970s. He is the president of Wolverine Software, which he founded in January 1976. In 2013 an interview with Jim was included as one of the initial video oral histories of computer simulation pioneers funded by the National Science Foundation (NSF) at the Computer Simulation Archive of the North Carolina State University Libraries. In the first part of his individual interview Jim describes what it was like to work at the U-M Computing Center in the late 1960s and early 1970s.

The link to the Computer Simulation Archive is http://d.lib.ncsu.edu/computer-simulation/ and the link to Jim's interview is http://d.lib.ncsu.edu/computer-simulation/videos/james-o-henriksen-interviewed-by-richard-e-nance-henriksen. The interview is an hour and 10 minutes in length and includes two discussions of the U-M Computing Center from 4:55 to 10:11 and from 58:06 to 1:00:26 (the rest of the interview is interesting too).

There is a short bio-sketch for Jim in the People section of the MTS Archive.
