Tim Berners-Lee, the Inventor of the World Wide Web
Sir Timothy John "Tim" Berners-Lee, (born 8 June 1955), also known as "TimBL", is an English computer scientist, best known as the inventor of the World Wide Web.Sir Tim Berners-Lee invented the World Wide Web in 1989 while working as a software engineer at CERN, the large particle physics laboratory near Geneva, Switzerland.
In 1936, Turing went to Princeton University in America, returning to England in 1938. He began to work secretly part-time for the British cryptanalytic department, the Government Code and Cypher School. On the outbreak of war he took up full-time work at its headquarters, Bletchley Park.
Here he played a vital role in deciphering the messages encrypted by the German Enigma machine, which provided vital intelligence for the Allies. He took the lead in a team that designed a machine known as a bombe that successfully decoded German messages. He became a well-known and rather eccentric figure at Bletchley.
