Colossus was the name of a computer that took over the world in a
movie ("Colussus: The Forbin Project").

Bletchley Park
From Wikipedia, the free encyclopedia
During World War II, codebreakers at Bletchley Park solved messages
from a large number of Axis code and cipher systems, including the
German Enigma machine. For this purpose, the Bletchley Park mansion,
pictured here, was soon joined by a host of other buildings.
Bletchley Park (also sometimes Station X) is an estate located in the
town of Bletchley, now part of Milton Keynes, England. During World
War II, Bletchley Park was the location of the United Kingdom's main
codebreaking establishment. Codes and ciphers of several Axis
countries were deciphered there, most famously the German Enigma. The
high-level intelligence produced by Bletchley Park, codenamed Ultra,
is frequently credited with aiding the Allied war effort and
shortening the war, although Ultra's effect on the actual outcome of
WWII is debated.
Wartime history
Early work on Enigma was performed here by Dilly Knox, John Jeffreys
and Alan Turing.
Bletchley Park is mainly remembered for breaking messages encyphered
on the German Enigma cypher machine, but its greatest cryptographic
achievement may have been the breaking of the German "Fish" High
Command teleprinter cyphers.
The intelligence produced from decrypts at Bletchley was code-named
"ULTRA". It contributed greatly to the Allied success in defeating
the U-boats in the Battle of the Atlantic, and to the British naval
victories of Battle of Cape Matapanand the Battle of North Cape.
When the United States joined the war, a number of American
cryptographers were posted to Bletchley Park.
Cryptanalysis
Among the famous mathematicians and cryptanalysts working there,
perhaps the most influential and certainly the best-known in later
years was Alan Turing.
In 1943, Colossus, the world's first programmable digital electronic
computer, conceived by Tommy Flowers and his crew at the British Post
Office, Dollis Hill facility, was built at Bletchley Park in order to
break the Fish Cyphers, in particular the Lorenz cipher.
