Caption: A female technician operating a bombe decyption machine in the US, May 1945. The bombe was an electro-mechanical device used by British and American cryptologists to help decipher German Enigma-machine-encrypted secret messages during World War II. The initial design of the bombe was produced in 1939 at the UK Government Code and Cypher School (GC&CS) at Bletchley Park by Alan Turing, with an important refinement devised in 1940 by Gordon Welchman.
