Edmond Debeaumarché

[1] Debeaumarché was born on 15 December 1906 in Dijon, and first wanted to become a pilot, but his eyesight was too weak and he joined the French postal service, PTT.

Traveling throughout France he created networks of resistance, and organized the sabotage of the enemy's telecommunications (the plans Potard and Violet—the latter involved cutting telephone cables before D-Day[3][4]).

In addition, he managed to procure the codebooks of the three secret codes used by Joseph Darnand and the Milice and used them to decipher copies of telegrams obtained from the central telegraph office in Paris.

[5] He was moved to the underground factory of Mittelbau-Dora which produced V-1 flying bombs and V-2 rockets, and posing as an electrical engineer was put to work in the manufacture of the V-1.

Maurice Naegelé, a Kapo in the tunnel assembly section, gained the trust of Debeaumarché by relating details of the resistance movement in France.
