Étienne Bazeries

Étienne Bazeries ( born August 21, 1846 in Port- Vendres, France, † November 7, 1931 ) was a French officer who had come with secret codes in conjunction, as he had as Charles Wheatstone and Playfair attempted coded messages in newspapers to decipher. Bazeries they decrypted and carried them before the officers' mess. Then Bazeries claimed to be able to decipher the French military code. He succeeded and the War Department changed the encryption system, but before the new procedure was introduced Bazeries had already deciphered it again.

Bazeries has now been assigned to the Chiffrierbüro the Foreign Ministry. During this time he began to take an interest for old secret messages. He deciphered texts that had been written at the time of Louis XIV. Among them was a letter whose decryption is considered by Bazeries as evidence that it is the man in the iron mask by Vivien de Bulonde.

1891 presented Bazeries his "cylinder" the French military authorities, a system for automatic encryption on the type of Jefferson roller.
