13087 Chastellux           Discovered 1992 July 30 by E. W. Elst at the European Southern Observatory.
François-Jean de Chastellux (1734-1788), author of De la félicité publique (1757), was a founder of the social sciences. He sought to determine whether society is susceptible to amelioration, if not to perfection. He cited America as an example of man's ability to progress through liberty, reason and equality.
