Charles Babbage, Alan Turing and Tim Berners-Lee rub shoulders with Henry VIII, William Blake, Lord Nelson and Robbie Williams as they vie to be selected among the top 10 greatest Britons of all time.
Babbage (1791-1871) is recognised as the father of computing for his work in inventing mechanical calculators.
Turing (1912-1954) published a theory that a machine, the Universal Turing Machine, could be built to solve all mathematical problems. During the Second World War he developed the Bombe, an engine that could decipher the codes generated by the Enigma machines used for German military radio communications.
Berners-Lee, the only living computer technologist to be nominated, invented the World Wide Web in 1989.
BBC2 viewers will have to wait for the Great Britons series to air in October to see whether any of these IT heroes make it into the final top 10 list.
