In 1932 Marian Adam Rejewski solved the Enigma machine, the main cipher device then in use by Germany. The success of Rejewski and his colleagues jump-started British reading of Enigma in World War II, and the intelligence so gained, code-named "Ultra", contributed, perhaps decisively, to the defeat of Nazi Germany. While studying mathematics at Poznań University, Rejewski attended a secret cryptology course conducted by the Polish General Staff's Cipher Bureau, which he joined full-time in 1932. http://en.wikipedia.org/wiki/Marian_Rejewski#Work_in_France_and_Britain Rejewski and Zygalski were inducted as privates into the Polish Army (they would eventually be promoted to lieutenant) and employed at cracking German SS and SD hand ciphers.
