World Wide Web
The World Wide Web, also known as the WWW and the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser in 1990 while employed at CERN near Geneva, Switzerland. The browser was released outside CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991.
Robert Cailliau
Robert Cailliau (born 26 January 1947) is a Belgian informatics engineer, computer scientist and author who proposed the first (pre-www) hypertext system for CERN in 1987 and collaborated with Tim Berners-Lee on www from before it got its name. He designed the historical logo of the WWW, organized the first International World Wide Web Conference at CERN in 1994 and helped transfer Web development from CERN to the global Web consortium in 1995. Together with Dr. James Gillies, Cailliau wrote "How the Web Was Born", the first book-length account of the origins of the World Wide Web.
