Victor A. Vyssotsky
Victor Alexander Vyssotsky 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. Later, Vyssotsky was the founding director of Digital's Cambridge Research Lab.
In 1960, Vyssotsky co-created the BLODI Block Diagram Compiler at Bell Labs. In 1961, together with Robert Morris Sr. and Doug McIlroy, he devised the computer game Darwin on an IBM 7090 at Bell Labs.
