William "Bill" Yeager (born June 16, 1940, San Francisco) is an American engineer. He is best known for being the inventor of a packet-switched, "Ships in the Night," multiple-protocol router in 1981, during his 20 year tenure at Stanford's Knowledge Systems Laboratory.[1][2] The code was licensed by upstart Cisco Systems in 1987 and comprised the core of the first Cisco IOS.[3]

He is also known for his role in the creation of the IMAP mail protocol, and for writing the ttyftp serial line file transfer program, which was developed into the MacIntosh version of the Kermit protocol at Columbia University. He has also worked 5 years for NASA Ames Research Center and 10 years at Sun Microsystems. At Sun as the CTO of Project JXTA he filed 40 US Patents, and as Chief Scientist at Peerouette, Inc., 2 US and 2 European Union Patents. He has so far been granted 20 US Patents 4 of which are on High Performance Email Servers, and 16 on P2P and distributed computing.

He received his bachelor's degree in mathematics from the University of California, Berkeley in 1964; his master's degree in mathematics from San Jose State University in San Jose, California, in 1966; and completed his doctoral course work at the University of Washington in Seattle, Washington in 1970. Then decided to abandon mathematics for a career in software engineering and research to the skepticism of his thesis advisor because Bill thought the future was in computing.
