Arne Beurling

1905 – 1986 Arne Beurling was a Swedish mathematician and professor of mathematics. In 1940 the mathematician broke the German code used for strategic military communications. This accomplishment is considered by many to be one of the greatest achievements in the history of cryptography. Using only teleprinter tapes and cipher text, he deciphered the code that the Germans believed impossible to crack in just two weeks. Beurling created a device that enabled Sweden to decipher German teleprinter traffic passing through Sweden from Norway on a cable. When Beurling was asked how he broke the code he replied, “A magician does not reveal his secrets”. Interesting Fact: Beurling code breaking allowed Swedish authorities to know about Operation Barbarossa (The codename for Nazi Germany’s invasion of the Soviet Union) before it occurred.
