In 1945 a Mathematics Division was established in the National Physical Laboratory (NPL) at Teddington, in order to coordinate facilities and techniques relating to machine aided computation. As regards building a stored-program computer, the NPL received most of its impetus from the disbanded COLOSSUS team from Bletchley Park, particularly Dr Alan Turing. In 1946 Turing presented to the Executive Committee of the NPL a complete design for a universal computer an Automatic Computing Engine (ACE). The proposal was accepted by the NPL director, Sir Charles Darwin, who probably thought of the ACE project in terms of a single national effort. The fragmentation of British technical personnel and resources after the Second World War, however, meant that this dream was never realised. Eventually a successful version of Turing's machine (the Pilot ACE) was built, which became the progenitor of the English Electric DEUCE; but by then a disillusioned Turing had left the NPL (leaving J.H. Wilkinson and E.A. Newman in charge), and his complicated instruction format ensured that his machine's influence was limited. Turing's design for the ACE, however, has its admirers.
