Vint Cerf

Vint Cerf is an American computer scientist widely known as one of the principal designers of the Internet, for co-creating the TCP/IP protocols with Robert Kahn in the 1970s. Working first at Stanford University and then at the Defense Advanced Research Projects Agency, Cerf and Kahn developed the Transmission Control Protocol and Internet Protocol as a way to let separate, differently designed computer networks interconnect and exchange data reliably, the technical foundation the modern Internet still runs on. Cerf also worked on the earlier ARPANET, the Internet's direct predecessor, and later helped found and served as founding president of the Internet Society, an organization promoting open standards for the Internet's continued development. He shared the Turing Award with Kahn in 2004 for pioneering work on internetworking, and he later held a long tenure at Google as its chief Internet evangelist, promoting continued expansion and openness of the network he helped design.
