a W a r D s Engineering prize honours internet and Web pioneers

Five engineers whose work, beginning in the 1970s, led to the internet and the World Wide Web have together won the inaugural Queen Elizabeth Prize for Engineering. Robert Kahn, Vinton Cerf, Louis Pouzin, Tim Berners-Lee and Marc Andreessen were announced on 18 March as the winners at the Royal Academy of Engineering in London. Kahn, Cerf and Pouzin receive the award for their contributions to the protocols that make up the fundamental architecture of the internet. French computer scientist Pouzin invented the datagram and designed an early packet communications network known as CYCLADES in the early 1970s. His work was broadly used by Americans Kahn and Cerf in the development of TCP/ IP. Berners-Lee created the World Wide Web at CERN in 1989 and American Marc Andreessen wrote the Mosaic browser that is credited with popularizing the Web. By sharing their work freely and without restriction these pioneers allowed the Tim Berners-Lee is reunited with the historic NeXT computer at CERN during celebrations Visit us at internet and the Web to be adopted rapidly for the 20th anniversary of the web in 2009 (CERN Courier May 2009 p24).
