In February 1944 a new machine called "Colossus" became operational; it was the world's first electronic computer. Colossus was designed and built in only ten months by Tommy Flowers of the G.P.O. (Post Office). This had far greater capacity and speed than the Robinson and so the whole breaking process became much faster.
The main engineering design was the work of Frank Morrell [4] at the Post Office Research Station at Dollis Hill in North London, with his colleague Tommy Flowers designing the "Combining Unit". [5] Dr C. E. Wynn-Williams from the Telecommunications Research Establishment at Malvern produced the high-speed electronic valve and relay counters. [5]

The Post Office Research Station was first established as a separate section of the General Post Office in 1909. [1] In 1921, the Research Station moved to Dollis Hill, north west London, initially in ex-army huts. [1] The main permanent buildings at Dollis Hill were opened in 1933 by Prime Minister Ramsay MacDonald. [1] [2]
