Tim Berners-Lee
In 2004, Berners-Lee was knighted by Queen Elizabeth II for his pioneering work. In April 2009, he was elected a foreign associate of the United States National Academy of Sciences. Named in "Time" magazine's list of the , Berners-Lee has received a number of other accolades for his invention. He was honoured as the "Inventor of the World Wide Web" during the 2012 Summer Olympics opening ceremony, in which he appeared in person, working with a vintage NeXT Computer at the London Olympic Stadium. He tweeted "This is for everyone", which instantly was spelled out in LCD lights attached to the chairs of the 80,000 people in the audience. Berners-Lee received the 2016 Turing Award "for inventing the World Wide Web, the first web browser, and the fundamental protocols and algorithms allowing the Web to scale".
Libwww
In 1991 and 1992, Tim Berners-Lee and a student at CERN named Jean-Francois Groff rewrote various components of the original WorldWideWeb browser for the NeXTstep operating system in portable C code, in order to demonstrate the potential of the World Wide Web. In the beginning libwww was referred to as the "Common Library" and was not available as a separate product. Before becoming generally available, libwww was integrated in the CERN program library (CERNLIB). In July 1992 the library was ported to DECnet. In the May 1993 World Wide Web Newsletter Berners-Lee announced that the Common Library was now called libwww and was licensed as public domain to encourage the development of web browsers. He initially considered releasing the software under the GNU General Public License, rather than into the public domain, but decided against it due to concerns that large corporations such as IBM would be deterred from using it by the restrictions of the GPL. The rapid early development of the library caused Robert Cailliau problems when integrating it into his MacWWW browser.
