John Shoch

John F. Shoch is an American computer scientist and venture capitalist who made significant contributions to the development of computer networking while at Xerox PARC, in particular to the development of the (PUP), an important predecessor of TCP/IP.

His contributions were significant enough to warrant including his name on the memorial plaque at Stanford University commemorating the "Birth of the Internet."

Shoch attended Stanford, where he earned a B.A. in political science (1971); he later went on to earn an M.S. (1977) and a Ph.D. (1979) in Computer Science from Stanford as well. His Ph.D. thesis was entitled "Design and Performance of Local Computer Networks".

He joined Xerox in 1971, working at PARC, where his research interests included , computer local area networks (in particular the Ethernet, which he helped develop), packet radio, programming languages, and various other aspects of distributed systems. His best-known work from that period, after the Ethernet and PUP, is on network worms; although the most famous incident involves one that ran out of control, they were actually early experiments in distributed computing over a network of loosely coupled machines.

In 1980, he became the assistant to the CEO of Xerox and director of the Corporate Policy Committee. In 1982, he moved on to become president of Xerox's Office Systems Division (which developed network-based office systems derived from research performed at PARC).
