The Enigma myth - Edmond Kern
The Enigma coding machine has been invented by Alexander Koch in 1919. This machine has been adopted by the Reichsmarine in 1926 and by the Reichswehr in 1928.
Thanks to the billions of available combinations, Germans blindly trusted their machine. They learned only in 1973 that their messages had been decoded.
The first messages were decoded in 1932 thanks to captain Gustave Bertrand from the french intelligence services, documents provided by Hans-Thilo Schmidt and to the polish Biuro Szyfrów. This research was reused by Alan Turing at the beginning of the Second World War.
Enigma operators have been order to destroy machines and coding books to prevent their enemies using it.Therefore only a few Enigma coding machines still exist nowadays.
This presentation will be performed in French and you will be able to see an authentic Enigma (and not a replica!) coding machine.
A french summary of the presentation is available at ENIGMA_CommuniquePresse_2023.pdf
