I first met George Michael at a conference, and on several occasions we had interesting discussions about various computers including the DEC PDP-1. He had been in poor health for several years, and passed away last Thursday. Some of his computing stories may be found at Stories of the Development of Large Scale Scientific Computing at Lawrence Livermore National Laboratory.
Here’s his obituary from insidebayarea.com:
