Professor Burks taught philosophy of science and logic, among other subjects, at the University of Michigan at Ann Arbor for nearly forty years (where he also earned his Ph.D. in philosophy), but may be best known for his pioneering work in computer science.   The NY Times obituary is here.  (Thanks to Michael Bishop for the pointer.)  A memorial notice from the Electrial Engineering Department at Michigan is here.   His profile from the Michigan Philosophy Department page is here.
