Background of Saint Vincent DePaul.
Born at Pouy, Gascony, France, in 1580, though some authorities have said 1576; died at Paris, 27 September, 1660.
Born of a peasant family, he made his humanities studies at Daxwith the Cordeliers, and his theological studies, interrupted by a short stay at Saragossa, were made at Toulouse where he graduated in theology. Ordained in 1600 he remained at Toulouse or in its vicinity acting as tutor while continuing his own studies. Brought to Marseilles for an inheritance, he was returning by sea in 1605 when Turkish pirates captured him and took him to Tunis. He was sold as a slave, but escaped in 1607 with his master, a renegade whom he converted.
On returning to France he went to Avignonto the papal vice-legate, whom he followed to Rome to continue his studies. He was sent back to France in 1609, on a secret mission to Henry IV; he became almoner to the Queen Marguerite of Valois, and was provided with the little Abbey of Saint-Léonard-de-Chaume. At the request of M. de Berulle, founder of the Oratory, he took charge of the parish of Clichy near Paris, but several months later (1612) he entered the services of the Gondi, an illustrious French family, to educatethe children of Philippe-Emmanuel de Gondi.
He became the spiritual director of Mme de Gondi. With her assistance he began giving missions on her estates; but to escape the esteem of which he was the object he left the Gondi and with the approval of M. de Berulle had himself appointed curé of Chatillon-les-Dombes (Bresse), where he converted several Protestantsand founded the first conference of charityfor the assistance of the poor.
He was recalled by the Gondi and returned to them (1617) five months later, resuming the peasant missions. Several learned Paris priests, won by his example, joined him. Nearly everywhere after each of these missions, a conference of charitywas founded for the relief of the poor, notably at Joigny, Châlons, Mâcon, Trévoux, where they lasted until the Revolution.
