The following details will be sufficient for these memoirs: The Chevalier Charles d'Eon de Beaumont (who was born in 1728) was an ex-captain of dragoons, employed in both the open and secret diplomacy of Louis XV.
When at the embassy in London he quarrelled with the ambassador, his superior, the Comte de Guerchy (Marquis do Nangis), and used his possession of papers concerning the secret diplomacy to shield himself.
It was when hiding in London, in 1765, on account of this business, that he seems first to have assumed woman's dress, which he retained apparently chiefly from love of notoriety.

In 1775 a formal agreement with the French Court, made by the instrumentality of Beaumarchais, of all people in the world, permitted him to return to France, retaining the dress of a woman.

He went back to France, but again came to England, and died there, at his residence in Millman Street, near the Foundling Hospital, May 22, 1710.
