Condorcet (kong-dor'-sa), Jean Marie Antoine Nicholas Caritat, Marquis de. Was born in 1743. Condorcet gained celebrity by his successful labors as a mathematician. His treatise on integral calculations, written when he was but 22 years of age, was eminently successful, and was considered to indicate a degree of knowledge seldom possessed at so early an age. He was the friend of D'Alembert and of almost all his illustrious contemporaries, as well as one of the disciples of Voltaire. Being appointed governor of the dauphin by the constituent assembly, he was successively called to the legislative body and to the convention; but subsequently denounced as a partisan of the Girondists, he was outlawed in 1793, and poisoned himself in 1794.
