Colossus was the world's first programmable (to a limited extent) digital electronic computer. It was built by the British Post Office Research Station at Dollis Hill, by Thomas Flowers and crew to a design by Max Newman and associates of Bletchley Park. It was primarily designed for cryptanalysis in an attempt to break one of the cyphers used by the German military for its most secure strategic communications during WWII.
