This computer was used at CERN by British scientist Tim Berners-Lee to devise the World Wide Web (WWW) in the late 1980s and early 1990s. In 1980, Berners-Lee spent six months as a consultant software engineer at CERN, the European particle Physics Laboratory in Geneva, during which time he wrote the programme 'Enquire', which formed the conceptual basis for the Web. In 1990, he began writing the first WWW server 'httpd' which was made available within CERN in December 1990, and on the Internet at large in 1991.
