Timothy John Berners-Lee

Early Life

Timothy John Berners-Lee was born on 8 June 1955 in London, England, the eldest of four children of Mary Lee Woods and Conway Berners-Lee, both mathematicians and computer scientists who had worked on the Ferranti Mark I, one of the first commercial computers. He grew up in a household full of talk about computers and mathematics, and as a boy he built a computer from spare parts and an old television set. He was educated at Emanuel School in London and then at Queen's College, Oxford, where he read physics and graduated with first-class honours in 1976.

Education

Berners-Lee studied physics at Queen's College, University of Oxford, graduating with a first-class Bachelor of Arts degree in 1976. He is a professorial research fellow at the University of Oxford and a professor emeritus at the Massachusetts Institute of Technology.

Career

Berners-Lee studied physics at Queen's College, Oxford, graduating in 1976, and worked as an engineer for Plessey Telecommunications and as a founding director of Image Computer Systems. In 1980 he spent six months as a contractor at CERN, where he built ENQUIRE, a prototype hypertext system for sharing information. He returned to CERN as a fellow in 1984 and in March 1989 submitted his proposal for the World Wide Web. His manager, Mike Sendall, wrote 'Vague, but exciting' on the cover and let him proceed. By the end of 1990 the first browser and server were running on a NeXT computer at CERN, and in August 1991 the first website went public. In October 1994 he moved to MIT and founded the W3C, which he has led ever since as director and now emeritus director. He is a professorial research fellow at the University of Oxford and a professor emeritus at MIT, and he continues to work on decentralising the Web, including the Solid project and the company Inrupt, founded in 2019.

Achievements

Berners-Lee's central achievement was the World Wide Web, invented in 1989 while he worked at CERN, the European particle-physics laboratory. His proposal, 'Information Management: A Proposal', joined two existing ideas, hypertext and the internet, into a system where documents could link to each other across computers. In 1990 he built all the pieces: HTML for writing pages, HTTP for transferring them, URLs for addressing them, the first web browser and the first web server. The first website, info.cern.ch, went public in August 1991, and in April 1993 CERN released the Web into the public domain, free for anyone to use. In 1994 he founded the World Wide Web Consortium (W3C) at MIT to develop open web standards. He received the 2016 Turing Award, the highest honour in computer science, was knighted in 2004, and was admitted to the Order of Merit in 2007.

• Invented the World Wide Web in 1989, while working at CERN, with a proposal for linking documents by hypertext
• Designed and built HTML, the language of web pages, HTTP, the protocol that transfers them, and the URL addressing system
• Built the first web browser and the first web server, WorldWideWeb, in 1990
• Opened the first website, info.cern.ch, in August 1991, making the Web public
• Founded the World Wide Web Consortium (W3C) at MIT in 1994 to keep web standards open and vendor-neutral
• Saw CERN release the Web into the public domain, royalty-free, on 30 April 1993
• Received the 2016 ACM Turing Award for inventing the Web, the first web browser, and the protocols that let it scale
• Was knighted in 2004 for services to the global development of the internet and admitted to the Order of Merit in 2007

Legacy

Berners-Lee is remembered as the inventor of the World Wide Web, the system that turned the internet from a network for specialists into a public space for information, commerce, learning and communication. He gave the Web away rather than patenting it: CERN released it into the public domain in 1993, and the W3C he founded has kept its standards open, so that no company owns the Web itself. That decision shaped the modern world more than any single invention of the late twentieth century. He continues to argue for a Web that protects privacy and gives users control of their own data, through the Solid project and his work at MIT and Oxford.

Contributions

Berners-Lee's contribution was to make the internet usable by everyone. The internet already existed in 1989, but it was hard to use and its information was locked in separate systems; his Web joined hypertext to the internet, so that any document could link to any other, anywhere in the world, with a click. He built the three technologies that made it work, HTML, HTTP and URLs, and then gave the whole system away, free and open. The result was the Web that now carries news, shopping, banking, education and social life, and the open standards he set up through the W3C are the reason any browser can read any website.
