Deciphering Marie Antoinette's Secret Letters

Speaker: Jacques Patarin
Date, Time: Fri, 22 Jan 2010 15:00

In this talk, we explain the encryption algorithm used by the Queen of France, Marie- Antoinette, to send letters to Axel von Fersen during the French Revolution. We give the complete deciphering of some letters for which we found differences with the text taken from historical books. We also provide the deciphering of one letter that seems to be unknown so far. The results we get bring new proofs on Marie-Antoinette's deep affection for Fersen. Finally, we mention some open questions about Marie-Antoinette's correspondence with Axel von Fersen.
