One of the "fathers of the Internet” - Vinton Gray Cerf

Vinton Gray Cerf - an American internet pioneer, who is recognized as one of "the fathers of the Internet", was born on June 23, 1943. 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. 

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. He was elected as the president of the Association for Computing Machinery in May 2012, and in August 2013 he joined the Council on CyberSecurity's Board of Advisors.

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.
