First Cryptographic Decoder

The first cryptographic decoder, Colossus I was built by Alan Mathison Turing, Maxwell H.A. Newman, and T.H. Flowers at the Government Code and Cipher School (GC and CS) Center at Bletchley Park, near London, England in December 1943. It was used to decipher German military messages encrypted on the Enigma machine. The Colossus is sometimes cited as the first electronic computer, as it contained some mechanical systems.
