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.
Dynamic web page
It is difficult to be precise about "dynamic web page beginnings" or chronology, because the precise concept makes sense only after the "widespread development of web pages": HTTP has been in use since 1990, HTML, as standard, since 1996. The web browsers explosion started with 1993's Mosaic. It is obvious, however, that the concept of dynamically driven websites predates the internet, and in fact HTML. For example, in 1990, before general public use of the internet, a dynamically driven remotely accessed menu system was implemented by Susan Biddlecomb, who was Director of Computer Support of the USC Health Care system at the University of Southern California BBS on a 16 line TBBS system with TDBS add-on.database.
