The Enigma was an electro-mechanical machine used for the encryption and decryption special orders by the Germans during WWII. The first Enigma was invented by German engineer Arthur Scherbius earielr during WWI. Breaking its code and deciphering the German's secret messages was one of the key points to winning the war. And the code was  broken by 3 Polish scientists: Mariana Rejewskiego, Jerzego Różyckiego i Henryka Zygalskiego. Some sources says that they only helped US scientist. Is this true or not, fact is, that without them breaking Enigma code would be impossible.
