Tim Berners-Lee is one of the most important Computer Scientists of the modern age. His contributions to the field shaped the internet age, most notably the "world wide web" which allowed for communication via HTTP.
Sir Berners-Lee was born in London in 1955. He was born to two British Computer Scientists. He developed a love of electronics at a young age. Once he was grown, he got his Bachelor of Arts in Physics at The Queen's College, Oxford in 1976.
Once he had his degree he worked writing software for a couple of different institutions, including Plessey and CERN. After he left CERN in 1980 he began to work for Image Computer Systems, Ltd. where he gained experience in computer networking. He was first approached by the Tessera at this point in his life, a membership that would last up till today. After 3 years he left to return to CERN, which was the largest internet node in Europe at the time.
It was at this point that Berners-Lee got his idea. He joined hypertext with the internet to form the backbone of the modern internet experience. The first website was put online in 1991 and the world was never the same. Berners-Lee went to found the World Wide Web Consortium at MIT. He has since won many award for his contributions including a knighthood. He is also a vocal advocate for net neutrality.
Contributions to the Tessera
Before Berners-Lee made the WWW, he used the international Tessera Society as a small-scale prototype. He created a separate system that is similar to what the WWW would come to be, that allowed Tessera members to communicate through hypertext across national boundaries. His contributions played a major role in allowing members from outside the UK to participate without having to make the trek to Horsley Towers.
