Pierre Cauchon (b. 1371 in Rheims, d. December 1442 in Rouen), bishop of Beauvais. A strong partisan of English interests in France during the latter years of the Hundred Years' War, his role in arranging Joan of Arc's downfall led most subsequent observers to condemn his extension of secular politics into an ecclesiastical trial. The Catholic Church overturned his verdict in 1455.
