(French: “Polytechnic School”), engineering school located originally in Paris but, since 1976, in Palaiseau, Fr., and directed by the Ministry of Defense. It was established in 1794 by the National Convention as the École Centrale des Travaux Publics (“Central School of Public Works”) under the leadership of Lazare Carnot and Gaspard Monge. It took its present name in 1795 and absorbed the state artillery school in 1802. Originally under the direction of the Ministry of the Interior, it was transformed into a military school by Napoleon (1804). In the past, most graduates became technical officers in the military forces; today most go into government service or business. There are faculties of mathematics, mechanical engineering, physics, chemistry, economics, and humanities and social sciences.
