Alan Sheltzer


The ground-breaking work of computer scientists Alan Sheltzer, Michael Brescia, Robert Hinden and Virginia Travers in Internet router technology, led to the creation of today’s Internet, as well as the design and development of Internet gateway protocols and packet forwarding and monitoring software. Messrs. Sheltzer, Brescia, Hinden and Ms. Travers are considered to be central figures in early router implementations and key contributors to the evolution of the Internet.

Dr. Sheltzer joined technology consultancy Bolt, Beranek and Newman (BBN) in 1979 to support its work for the U.S. Defense Advanced Research Projects Agency. He helped develop and deploy Internet gateways, now called routers, in Europe and the U.S., and worked on improving routing for an expanding Internet. Dr. Sheltzer is an IEEE Member. He holds a bachelor’s in physics from Brandeis University and a Ph.D. in Computer Science from UCLA.
