FRANCOIS-PIERRE MAINE DE BIRAN - GONTHIER (1766-1824), French philosopher, was born at Bergerac, on the 29th of November, 1766.
On the breaking up of the gardes du corps Biran retired to his patrimonial inheritance of Grateloup, near Bergerac, where his retired life preserved him from the horrors of the Revolution.
After having taught Greek in the university for twelve months, he removed to Bordeaux, where he was soon appointed a regent in the college of Bergerac. He did not remain long at Bordeaux, but accepted the offer of a chair of philosophy at Sedan, where he passed two years.
On several occasions St Bernard was begged to fight the innovator on the scene of his exploits, and in 1145, at the instance of the legate Alberic, cardinal bishop of Ostia, he set out, passing through the diocese of Angouleme and Limoges, sojourning for some time at Bordeaux, and finally reaching the heretical towns of Bergerac, Perigueux, Sarlat, Cahors and Toulouse.
