Pacareau, Pierre a French prelate of Jansenistic tendency, was born at Bordeaux. Sept. 2, 1716; and after excellent educational advantages, having made himself master of the Romance, the classical, and the Shemitic tongues, he took holy orders. He became at once a popular preacher, and was honored with a canonicate in the metropolitan church of his native place. An earnest sympathizer with the Jansenists, he greeted the changes which the approaching revolution wrought in Church and State, and was elected bishop March 14, 1791, under the new constitution. He took no part in state affairs, and but rarely had occasion to perform the duties of his ecclesiastical office. He died Sept. 5, 1797, at Bordeaux. He was much prized by his contemporaries for his kindness and benevolence. He wrote Nouvelles considerations sur l'usure et le pret az l'interet (Bord. 1787, 8vo).
