BEAUSOBRE, ISAAC DE, a learned Protestant writer, of French original, was born at Niort in 1659. He was forced into Holland to avoid the execution of a sentence upon him, which condemned him to make the amende honorable; and this for having broken the royal signet, which was put upon the door of a church of the Reformed, to prevent the public profession of their religion. He went to Berlin in 1694; was made chaplain to the king of Prussia, and counsellor of the royal consistory. He died in 1738, aged 79, after having published several works: as, 1. Defense de la Doctrine des Reformes. 2. A Translation of the New Testament and Notes, jointly with M. Lenfant; much esteemed by the Reformed. 3. Dissertation sur les Adamites de Boheme; a curious work. 4. Histoire Critique de Monarchie et du Monachisme, 2 tom. in 4to. This has been deemed by philosophers an interesting question, and nobody has developed it better than this author. 5. Several dissertations in the Bibliothèque Britannique. — Mr Beausobre had strong sense with profound erudition, and was one of the best writers among the Reformed; he preached as he wrote, and he did both with warmth and spirit.
