List of Internet pioneers
Nicola Pellow, one of the nineteen members of the "WWW Project" at CERN working with Tim Berners-Lee, is recognized for developing the first cross-platform internet browser, Line Mode Browser, that displayed web-pages on dumb terminals and was released in May 1991. She joined the project in November 1990, while an undergraduate math student enrolled in a sandwich course at Leicester Polytechnic (now De Montfort University). She left CERN at the end of August 1991, but returned after graduating in 1992, and worked with Robert Cailliau on MacWWW, the first web browser for the classic Mac OS.
Web search engine
Internet search engines themselves predate the debut of the Web in December 1990. The Who is user search dates back to 1982 and the Knowbot Information Service multi-network user search was first implemented in 1989. The first well documented search engine that searched content files, namely FTP files was Archie, which debuted on 10 September 1990.
