High Quality Content by WIKIPEDIA articles! Odet de Foix, Vicomte de Lautrec (1485 15 August 1528) was a French military leader. He gained the reputation of a gallant and able soldier, but this scarcely seems to be justified by the facts; though he was always badly used by fortune. The branch of the Viscounts of Lautrec originated with Pierre, the son of John III of Foix; Pierre's elder brother was Gaston IV of Foix.
