- Henri Braquenié
Henri Braquenié was an
interbellum andWorld War II French Air Force officer andcryptanalyst .Captain Braquenié attended, with French Major
Gustave Bertrand and another French Army officer, theJanuary 9 -10,1939 ,Paris meeting of French, Polish and Britishmilitary intelligence officers convened to discuss progress (none had occurred in France or Britain) ondecryption of German Enigmacipher s.Braquenié also participated with Bertrand in the trilateral
July 25 ,1939 ,Warsaw meeting at which the Polish Cipher Bureau disclosed its achievements in breaking Enigma ciphers (since December 1932).During the period of the
Phony War (October 6 ,1939 –May 10 ,1940 ) Braquenié served as deputy to the French chief, Bertrand, of "PC Bruno ," the Franco-Polish radio-intelligence andcryptology center outside Paris.On
December 3 -7,1939 , Braquenié accompanied the chief of the Polish cryptologic team, Lt. Col.Gwido Langer , toLondon andBletchley Park . At Bletchley, Braquenié established the procedures for mutualteletype exchange of information, especially of solved daily Enigma keys. In 1975, shortly before his death, he disclosed that, to ensure the absolute security of the information exchanges, the allied cryptologic services used Enigma itself as their cipher. Braquenié, personally responsible for the Bruno-Bletchley correspondence, followed the standard procedure of padding messages with innocuous verbiage, and habitually closed them with a "Heil Hitler!"Following France's capitulation in June 1940, Braquenié evacuated south to unoccupied,
Vichy France with other Bruno staff, and subsequently served at the "Cadix" center that was then established nearUzès , not far from theMediterranean Sea .References
