Gene M. Amdahl, chief architect of IBM's System/360 mainframe [ibm.com] and later the creator of the IBM plug-compatible mainframe vendor that bore his name, has died aged 92.
Amdahl was born in South Dakota, earning a bachelor's degree in engineering physics at the state university in 1948.
In 1950, as a PhD student at the University of Wisconsin-Madison, he and Charles H. Davidson designed a digital computer. In 1952, the year Amdahl received his doctorate in theoretical physics, the university began building the computer, the Wisconsin Integrally Synchronized Computer (WISC) [wikipedia.org].
