Born in Nantes. Master of a school of philosophy (1091-1113). Studied under Anselm of Laon (1113-17). Teacher of philosophy (1117-21). Secretly married Hélöise, thus incurring the anger of her uncle Fulbert, whose hired bravos mutilated him so that he was incapable of ecclesiastical preferment. He withdrew to a monastery. His nominalistic teachings were declared heretical in 1121. He wandered from monastery to monastery and was declared a heretic in 1140. He died while on the way to Rome to defend himself. His body was given to Hélöise, who was then the prioress of the convent of the Paraclete at Nogent-sur-Seine. She buried him in the oratory there. Later, she was interred beside him. The ashes of both were brought to Paris in 1800 and interred in one sepulchre at Père la Chaise in 1817.
