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.
World Wide Web Wanderer
The World Wide Web Wanderer, also referred to as just the Wanderer, was a Perl-based web crawler that was first deployed in June 1993 to measure the size of the World Wide Web. The Wanderer was developed at the Massachusetts Institute of Technology by Matthew Gray, who, as of 2017, has spent a decade as a software engineer at Google. The crawler was used to generate an index called the "Wandex" later in 1993. While the Wanderer was probably the first web robot, and, with its index, clearly had the potential to become a general-purpose WWW search engine, the author does not make this claim and elsewhere it is stated that this was not its purpose. The Wanderer charted the growth of the web until late 1995.
