French Dominican. He was a contributor to F. de Lamennais's periodical L'Avenir, but severed his connexion when it was condemned in 1832. In 1835–6 he gave his first two series of Conferences or sermons at Notre-Dame; they drew a vast congregation, largely from the intelligentsia. His political liberalism and Ultramontane theology aroused distrust, however, and he retired to Rome. In 1839 he entered the Dominican Order with the idea of restoring it in France; in 1843 he established at Nancy the first Dominican house in France since the suppression of the Order in 1790, and in 1852 he founded the teaching Third Order.
