ABBADIE, JACQUES: Protestant apologist; b. at Nay (10 m. s. by e. of Pau), France, 1654 (?); d. at Marylebone, London, 1727. He studied in the French Reformed Church academies of Saumur and Sedan, and early showed much talent. On invitation of the elector of Brandenburg, he became pastor of the French Reformed congregation in Berlin in 1680; after the death of the elector (1688), he followed Marshal Schomberg to England; and became pastor of the French church in the Savoy, London, in 1689. In 1699 he was made dean of Killaloe, Ireland. His Traite de la verite de la religion Chretienne (vols. i. and ii., Rotterdam, 1684; vol. iii., 1689: Eng. transl., 2 vols., London, 1694), became one of the standard apologetic works in French literature. Of his other works, L'Art de se connaitre soi-meme (Rotterdam, 1692), giving an outline of his moral system, attracted much attention and was warmly defended by Malebranche.
