Vinton Gray Cerf
Vinton Gray "Vint" Cerf (/'s?rf/; born June 23, 1943) is an American computer scientist, who is recognized as one of "the fathers of the Internet", sharing this title with American computer scientist Bob Kahn. His contributions have been acknowledged and lauded, repeatedly, with honorary degrees and awards that include the National Medal of Technology, the Turing Award, the Presidential Medal of Freedom, and membership in the National Academy of Engineering.
In the early days, Cerf was a program manager for the United States Department of Defense Advanced Research Projects Agency (DARPA) funding various groups to develop TCP/IP technology. When the Internet began to transition to a commercial opportunity during the late 1980s, Cerf moved to MCI where he was instrumental in the development of the first commercial email system (MCI Mail) connected to the Internet.
Cerf was instrumental in the funding and formation of ICANN from the start. He waited in the wings for a year before he stepped forward to join the ICANN Board, eventually becoming chairman.
Cerf went to Van Nuys High School along with Jon Postel and Steve Crocker; he wrote the former's obituary. Both were also instrumental in the creation of the Internet.
Cerf is also known for his sartorial style, typically appearing in three-piece suit--a rarity in an industry known for its casual dress norms.
