Jean du Vergier de Hauranne
French theologian

Jean du Vergier de Hauranne, the Abbé (Abbot) of Saint-Cyran (1581 – 6 October 1643), was a French Catholic priest who introduced Jansenism into France.
Life
Born in the city of Bayonne to a family of Gascon and Basque merchants, Vergier studied with the Jesuits of Agen. At the age of sixteen he was sent to study at the Sorbonne, and then took up theology at the Catholic University of Leuven. There he formed a friendship with Cornelius Jansen and, as the wealthier of the two, became Jansen's patron for a number of years, getting Jansen a job as a tutor in 1606. Two years later, he obtained for Jansen a position teaching at the episcopal college back in Bayonne. The duo spent 1611–1614 there, in seclusion in a house belonging to his family, where they studied the Church Fathers together, with a special focus on the thought of Augustine of Hippo, until Jansen left Bayonne in 1614 to return to the Dutch Republic.
In 1617 Vergier left Bayonne at the invitation of Henri-Louis Chasteigner de La Roche-Posay, the Bishop of Poitiers, where he soon became a leading figure of the diocese. He was ordained a priest in 1618. In 1620 he became the commendatory abbot of the Abbey of Saint-Cyran and was thus generally known as the Abbé de Saint-Cyran for the rest of his life. The new commendatory prelate resided little in his abbey.
