Enigma Cipher MachineShow/Hide_Details
During World War II Bletchley Park was the home of the secret Government Code and Cypher School. This was the centre of British code-breaking The code-breakers were specially chosen from among the cleverest people in the country. Some were brilliant mathematicians or linguists such as Including Alan Turing, a Cambridge mathematician who helped to invent the world's first computer (Colossus) at Bletchley Park. Among the ciphers that were broken were Enigma and Lorenz. Against seemingly insurmountable odds, the code breakers devised methods to allow them to successfully read enemy codes, often within a few hours of the messages being received by the outlying Y-stations. . To break the code they had to compare the message with others to see if they could work out exactly how the U-boat commanders had set their Enigma rotor wheels and plug board settings that day. This meant trying - to find the correct answer out of 150,000,000,000,000,000,000 possibilities - and starting from scratch each day.
