Very Rare 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.
Mathematician Margaret Rock joined Bletchley Park on 15 April 1940 and was selected to work in Dillwyn (Dilly) Knox’s Research Section, a small team tasked with breaking untried ‘Enigma machine variations’ and later the German Abwehr Enigmas. Margaret received an MBE for her services to the country in 1945.
14 Mar 40: The first "bombe" decipher machine becomes operational at Bletchley Park in England. It not only plays an important role in the outcome of World War II, but will lead directly to today's modern computing. #WWII #History
Alan Turing and his machines - fresh insights into the enigma
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.
