WWII Enigma Cipher Machine. This highly important three-rotor Enigma deciphering machine was used by the Nazis during World War II. It is believed that acquisition of an Enigma, and the subsequent deciphering of the German codes by the Allies, shortened the war in Europe by at least two years. Examples of Enigma machines are exceptionally rare and almost all known models are in museums.
The Bombe was an electromechanical device used by British cryptoanalysts to help decipher German Enigma-machine-encrypted signals during World War II. The function of the bombe was to discover some of the daily settings of the Enigma machines on the various German military networks, thus helping to shorten the war and save many lives. A lot of early research work was done by Marian Rejewski and others, who proposed the idea of a 'cryptologic bomb'.
Front of a ‘bombe’ code-breaking machine at Bletchley Park, 1943. The electromagnetic machines were used to determine the plugboard settings of German Engima machines. This involved multiple ‘bombes', piles of perforated papers and production lines of analysts to interpret the results.
It is hard to overstate the importance of Alan Turing, the British mathematician who died in 1954. He was a hero in science, for one. Turing invented the concepts that underlie modern computers and artificial intelligence. And he was a hero in war: He was a vital part of the British cryptographic team at Bletchley Park that cracked the German Enigma code during World War II.

Alan Turing : The codebreaker who saved 'millions of lives' / Jack Copeland @bbcnews | Alan Turing - the Bletchley Park codebreaker - would have been 100 years old on 23 June had he lived to the present day. To mark the occasion the BBC commissioned a week-long series of articles to explore his many achievements. This second essay examines the impact the British mathematician had on the outcome of World War II | #alanturingyear
