Names to Remember
Tim Berners-Lee invented the World Wide Web in late 1990 while working at CERN, the European Particle Physics Laboratory in Geneva, Switzerland. He wrote the first WWW client (a browser-editor running under NeXTStep) and the first WWW server along with most of the communications software, defining URLs, HTTP and HTML. He is a graduate of Oxford University.

He left NCSA in March 1994 and formed a company later known as Netscape Communication Corporation.
