....wrote HP Solve, played the Tiple, could deliver a baby, known for his cooking.... He sounds like he could have been the model for the man in Heinlein's quote Specialization is for Insects. ▼

He did HP-Solve? Hope he left at least some write ups about it. HP-Solve is - not only for me - a milestone. Sad.....Mike

Chris Bunsen was behind the HP Solve user interface of the HP-18C and subsequent calculators: http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1987-08.pdf ( History and Inspiration of the Solve Interface, by Chris M. Bunsen, can be found at page 10) The SOLV key, a primary function on the HP-28S, was one of the things that impressed me back in the day. Still today a joy to use! The algorithm itself was based upon Prof. Kahan's, I think: http://www.eecs.berkeley.edu/~wkahan/Math128/SOLVEkey.pdf It's really bad news when a creative and active mind goes away unexpectedly. Rest in peace, Mr. Bunsen! Gerson.
