Saint-Simon

CLAUDE HENRI, COMTE DE, (se'mawn(g,) a French philosopher, B. in Paris, served in the American army under Gen. Washington, and, after the French Revolution, expended a large part of his fortune in an abortive attempt at establishing a large scientific and industrial school on the basis of certain visionary ideas ofhis own regarding the advancement of human civilization. In 1807 he published an Introduction to the Scientific Labours of the Nineteenth Century; and, in 1814, The Reorganization of European Society. In 1825, he appeared as author of a remarkable work entitled New Christianity, in which he laid down as a dictum the progre ive nature of Christianity. His doctrines attracted so many adherents, that a new philosophical sect grew out of them, among the most eminent members of which were August in Thierry, August in Comte, and Michel Chevalier. D. 1825. - LOUIS DE ROUVROY, DUC DE ST. S., a French author and diplomatist, B. 1695, belonged to the same family as the foregoing, and filled many high offices during the Regency of the Duc d'Orleans. His reputation, however, chiefly rests upon his Memoirs of the Age of Louis XIV. and the Regency, a work in 20 vols., of high historical fidelity and literary merit, and of which an English edition appeared in 1857. D. 1755. [s. 790]
