A Few Great, Often Forgotten White Moments.

“Less than six weeks before World War II began, on September 3, 1939, Lieutenant Gwido Langer, head of the Polish Central Staff’s cipher bureau invited British and French intelligence chiefs to a meeting at his secret cryptology centre at Pyry in the Kabaty woods near Warsaw.

There he revealed to them that his team, Rejewski, Zygalski, and Rozycki, had cracked the Enigma code seven years before and had been reading German messages ever since. This was five years before Alan Turing had even started studying cryptology – he was still working on a degree in mathematical logic at Princeton University in the United States.

The GC&CS (Government Code and Cipher School) in Buckinghamshire became the Allies’ center for dealing with the war-induced changes in the enciphered messages.”
