IBM Advanced Computing Systems -- Staff List

Project Staff

The architecture team was an extremely smart, talented group. I recall someone from Livermore coming to visit once and commenting that he had not seen such a high concentration of talent since the Manhattan Project. As you might imagine IBM had a lot of smart people, but this group was in a class by itself.
