In March 1989, while a software engineer at CERN, Berners-Lee submitted a proposal titled 'Information Management: A Proposal' to manage the lab's tangled documentation. His manager Mike Sendall famously scrawled 'vague, but exciting' on it and let him proceed. By late 1990 he had written the first web browser, server, and the HTTP, HTML, and URL standards, inventing the World Wide Web.
Timothy John Berners-Lee was born in London on June 8, 1955, to Mary Lee Woods and Conway Berners-Lee, mathematicians who worked on the Ferranti Mark 1, one of the first commercial computers. A childhood trainspotter, he learned electronics tinkering with model railways. He earned a first-class physics degree from Oxford in 1976.
Working at CERN in Geneva, he proposed a global hypertext system in 1989 to link the lab's scattered research. By 1991 he had built the browser, server, and the HTTP, HTML, and URL standards that define the web. Crucially, he insisted the technology remain open and royalty-free for everyone.
In 1994 he founded the W3C at MIT to steward web standards, and later launched the World Wide Web Foundation and the Solid project. Knighted in 2004 and awarded the Turing Award in 2016, he has spent recent years campaigning for privacy and user control over personal data.
