Victor Alexander Vyssotsky (February 26, 1931 – December 24, 2012) was a mathematician and computer scientist. He was the technical head of the Multics project at Bell Labs and later executive director of Research in the Information Systems Division of AT&T Bell Labs. Multics, whilst not particularly commercially successful in itself, directly inspired Ken Thompson to develop Unix.[3] Later, Vyssotsky was the founding director of Digital's Cambridge Research Lab.
