Robert Elliot "Bob" Kahn (born December 23, 1938)to parents Beatrice Pauline and Lawrence Kahn. Robert was an American electrical engineer, who, along with Vint Cerf, invented the Transmission Control Protocol (TCP) and the Internet Protocol (IP), the fundamental communication protocols at the heart of the Internet.
After receiving an engineering degree from City College of New York in 1960, Kahn received a master’s degree (1962) and a doctorate (1964) in electrical engineering from Princeton University. Immediately after completing his doctorate, Kahn worked for Bell Laboratories and subsequently served as an assistant professor of electrical engineering at the Massachusetts Institute of Technology (MIT) from 1964 to 1966. However, it was his role as a senior scientist at Bolt Beranek & Newman (BB&N), an engineering consulting firm located in Cambridge, Massachusetts, that brought Kahn into contact with the planning for a new kind of computer network, the ARPANET.
Robert Kahn was instrumental in the creation of the Internet, from its earliest inception as ARPANET, a private/public collaboration between Bolt Beranek and Newman (BBN) and the Defense Advanced Research Projects Agency (DARPA). Kahn would straddle the divide, first working at BBN and eventually becoming the director of DARPA. He was also critical in transforming Arpanet into the full-fledged Internet.
