Robert (Bob) Kahn

Robert (Bob) Kahn, along with Vinton Cerf, is co-designer of theTCP/IP Internet network protocol. Kahn laid the open architecture foundations for the TCP/IP protocol, providing the Internet with one of its most distinctive features and what has proven to be a key advantage. Kahn obtained a Ph.D. degree from Princeton University in 1964, worked for a while at AT&T Bell Laboratories, and then became an Assistant Professor of Electrical Engineering at MIT. He later went to work at Bolt Beranek and Newman, and helped build the Interface Message Processor.
In 1972, Kahn was hired by Lawrence Roberts at the IPTO to work on networking technologies, and in October he gave a demonstration of an ARPANET network connecting 40 different computers at the International Computer Communication Conference, making the network widely known for the first time to people from around the world. At the IPTO, Kahn worked on an existing project to establish a satellite packet network, and initiated a project to establish a ground-based radio packet network. These experiences convinced him of the need for development of an open-architecture network model, where any network could communicate with any other independent of individual hardware and software configuration.
