Gene Amdahl

Gene Myron Amdahl (born November 16, 1922) is a computer scientist, chiefly known for his work on mainframes at IBM and others.

Born in Flandreau, South Dakota. After serving in the Navy during WW II he completed a degree in engineering physics at South Dakota State University. He went on to study theoretical physics at the University of Wisconsin and completed his doctorate there in 1952, creating his first computer, WISC[?]. He went straight from Wisconsin to a well paid position at IBM.

At IBM he worked on the IBM 704, the IBM 709, and then the Stretch project, the basis for the IBM 7030. He left IBM in 1956 but returned in 1960. On his return he worked on the System/360 architecture and became an IBM fellow (1965) and head of the ACS Laboratory in Menlo Park, California. He left IBM again in 1970, after his ideas for computer development were rejected, and set up Amdahl Corporation[?] in Sunnyvale, California with aid from Fujitsu. Competing with IBM in the mainframe market the company manufactured plug compatible mainframes, shipping its first machine in 1975 - the Amdahl 470 V6, a cheap and faster replacement for the System 360/165.

Amdahl left his company in 1980 to set up Trilogy Systems[?]. With over $200 million in funds Trilogy was aimed at designing an intergrated chip for even cheaper mainframes. The chip development failed and in 1985 Trilogy merged into Elxsi Corporation[?]. Elxsi also did poorly and Amdahl left in 1989, having already founded his next venture, Andor International[?], in 1987.

Andor hoped to compete in the mid-sized mainframe market, using improved production techniques to make smaller more efficient machines. Production problems and strong competition led the company into bankruptcy by 1995.

Ever determined, Amdahl co-founded Commercial Data Servers[?] in 1996, again in Sunnyvale. Again developing mainframe-like machines but this time with new super-cooled processor designs and aimed at smaller systems. When did this company fold?
