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 PARC Universal Protocol (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."
[1] He joined Xerox in 1971, working at PARC, where his research interests included internetwork protocols,[2] 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.
[4] He has also taught at Stanford University, is a member of the ACM and the IEEE, and serves as a trustee for the Computer History Museum.
