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
In December 1974 he started working at CERN as a Fellow in the Proton Synchrotron (PS) division, working on the control system of the accelerator. In April 1987 he left the PS division to become group leader of Office Computing Systems in the Data Handling division. In 1989, Tim Berners-Lee proposed a hypertext system for access to the many forms of documentation at and related to CERN. Berners-Lee created the system, calling it World Wide Web, between September and December 1990. During this time, Cailliau and he co-authored a proposal for funding for the project. Cailliau later became a key proponent of the project, running several projects to create and support browsers on different operating systems including various UNIX flavours and Classic Mac OS. With Nicola Pellow he helped develop the first web browser for the Classic Mac OS operating system called MacWWW.
