Career


While being an independent contractor at CERN from June to December 1980, Berners-Lee proposed a project based on the concept of hypertext, to facilitate sharing and updating information among researchers.[11] While there, he built a prototype system named ENQUIRE.[12]
After leaving CERN in 1980, he went to work at John Poole's Image Computer Systems, Ltd, in Bournemouth, England.[13]The project he worked on was a real-time remote procedure call which gave him experience in computer networking.[13] In 1984 he returned to CERN as a fellow.[12]
In 1989, CERN was the largest Internet node in Europe, and Berners-Lee saw an opportunity to join hypertext with the Internet: "I just had to take the hypertext idea and connect it to the Transmission Control Protocol and domain name systemideas and—ta-da!—the World Wide Web."[14] “Creating the web was really an act of desperation, because the situation without it was very difficult when I was working at CERN later. Most of the technology involved in the web, like the hypertext, like the Internet, multifont text objects, had all been designed already. I just had to put them together. It was a step of generalizing, going to a higher level of abstraction, thinking about all the documentation systems out there as being possibly part of a larger imaginary documentation system.”[15] He wrote his initial proposal in March 1989, and in 1990, with the help ofRobert Cailliau (with whom he shared the 1995 ACM Software System Award), produced a revision which was accepted by his manager, Mike Sendall.[16] He used similar ideas to those underlying the ENQUIRE system to create the World Wide Web, for which he designed and built the first Web browser, which also functioned as an editor (WorldWideWeb, running on the NeXTSTEP operating system), and the first Web server, CERN HTTPd (short for Hypertext Transfer Protocol daemon).
