Ron Srodawa
Ron Srodawa passed away on January 1, 2014

Ron died of complications of Alzheimer's disease. Ron's obituary is available here. The Srodawa Family would like memorials to be sent to the Alzheimer’s Foundation, Southfield, Michigan, in lieu of flowers, at http://www.alz.org/. Condolences may be sent to apseyfuneralhome.net.

Ron earned his Bachelor of Science degree (Magna cum Laude, 1965) from the University of Detroit, a Master of Arts degree from The University of Michigan (Mathematics, 1966) and a Doctor of Philosophy in Computer and Communications Sciences from the University of Michigan in 1972. At the University of Michigan 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 at Wayne State University in 1971 (while completing his doctorate) in Mathematics, later becoming an Assistant Professor and playing a critical role in building the department by serving as acting Department Chair. He moved to Oakland University as Associate Professor of Engineering and Computer Science in 1982. 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.
