BERTHIER, GUILLAUME FRANCOIS: French Jesuit; b. at Issoudun (130 m. s. of Paris), department of Indre, Apr. 7, 1704; d. at Bourges Dec. 15, 1782. He joined the Jesuits in 1722. He added six volumes (Paris, 1749) to the twelve already completed by Longueval, Fontenay, and Brumoy of the Histoire de l'église gallicane, bringing the narrative down to 1529; from 1745 to 1762 he edited the Mémoires de Trévoux and displayed much moderation as well as learning under attacks from the Encyclopedists and Voltaire. After the expulsion of his order from France in 1762 he was appointed tutor to the princes afterward Louis XVI and Louis XVIII, but had to leave the country in 1764; after an absence of ten years he returned to Bourges. He translated the Psalms (8 vols., 1785) and the Book of Isaiah (5 vols., 1788-89) into French with notes. His Œuvres spirituelles were published at Paris in five volumes in 1811.
