Sir Timothy John "Tim" Berners-Lee, also known as "TimBL", is an English computer scientist, MIT professor and the inventor of the World Wide Web. He made a proposal for an information management system in March 1989 and on 25 December 1990, with the help of Robert Cailliau and a young student at CERN, he implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet.
Berners-Lee is the director of the World Wide Web Consortium (W3C), which oversees the Web's continued development. He is also the founder of the World Wide Web Foundation, and is a senior researcher and holder of the 3Com Founders Chair at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL). He is a director of The Web Science Research Initiative (WSRI), and a member of the advisory board of the MIT Center for Collective Intelligence.
In 2004, Berners-Lee was knighted by Queen Elizabeth II for his pioneering work. In April 2009, he was elected a foreign associate of the United States National Academy of Sciences.
