Jesuit who assisted St. Margaret Mary Alacoque in establishing the devotion to the Sacred Heart.

Educated by the Jesuits of Lyon, he entered their novitiate at Avignon in 1658 and subsequently studied theology at the Collège de Clermont, Paris. After ordination he was appointed to the chair of rhetoric in the Collège de la Trinité at Lyon (1670–73). In 1675 he became superior of the Jesuit college at Paray-le-Monial, where he spiritually directed Margaret Mary. In 1676 he was appointed court preacher to Mary of Modena, who had become Duchess of York by marriage with the future King James II of England, and he took up his residence in St. James's Palace, London. Falsely accused by a former protégé of complicity in Titus Oates's “ Popish Plot,” he was imprisoned for five weeks and, when released, was obliged to return to France, where he died an invalid under the care of Margaret Mary. He was beatified by Pope Pius XI on June 16, 1929.
