Charles-Geneviève-Louis-Auguste-André-Timothée d'Éon de Beaumont, usually known as the Chevalier d'Éon, was born in October 1728 in Burgundy to a minor noble family. Due to their androgynous physical characteristics and natural abilities as a mimic they served as a French diplomat and spy in England and Russia. For the first 49 years of their life they appeared publicly as a man but after 1777 lived as a woman.
