Leverrier or Le Verrier, Urbain Jean Joseph 1811-77
French astronomer
Born in St Lô, Normandy, he became teacher of astronomy at the Polytechnique in 1836. His Tables de Mercure and several memoirs gained him admission to the Academy in 1846. From disturbances in the motions of planets he inferred the existence of an undiscovered planet and calculated the point in the heavens where, a few days afterwards, Neptune was actually discovered by Johann Gottfried Galle at Berlin (1846). Elected in 1849 to the Legislative Assembly, he became counter-revolutionary. In 1852 Louis Napoleon (Napoleon III) made him a senator and in 1854 he succeeded François Arago as director of the observatory of Paris.
