Emmanuel Louis Henri De Launay Antraigues, count d; a French adventurer and secret agent, born at Villeneuve-de-Berg about 1755, assassinated near London, July 22, 1812. He was a patron of science, letters, and art, figured con-spicuously in aristocratic circles, where in 1788 he was called the handsome conspirator, and wrote against the nobility. After his election in 1789 as deputy to the states general he soon returned to royalist doctrines, and leaving France in 1790, was subsidized by foreign governments to intrigue against the revolution. His name became notorious in the conspiracies against Napoleon, who had him arrested in Italy in 1797, with documents incriminating Pichegru. He escaped, went to St. Petersburg, joined the orthodox Greek church, and received a pension and the office of chancellor of the Russian legation at Dresden (1803), whence he was expelled by order of Napoleon, against whom he had published a famous diatribe (Fragment du 18me lure de Polybe, trouxe sur le Mont Athos). He next betrayed Russia by revealing to Canning the secret articles of the treaty of Tilsit, and received a large pension from the English government; but Napoleon's detectives having, as was supposed, received copies of these documents through his valet Lorenzo, the latter, fearing the consequences of his treachery, assassinated his master and his wife, and then shot himself.
