Lacroix, SYLVESTRE FRANCOIS

Lacroix, SYLVESTRE FRANCOIS, a French mathematician, was born in Paris in 1765, taught mathematics from 1787 in different educational establishments connected with the army, then in the Normal School, the Polytechnic, the University of France, and the Collège de France successively. He died on 25th May 1843. He is not remarkable for original discovery in mathematical science, but deserves to be remembered for his Traité du Calcul Différentiel et Intégral (Paris, 1797; 7th ed. 1867), and its continuation, Traité des Différences et des Séries (1800), which are complete compilations of the results of all previous research.
