Camille Flammarion, a French astronomer, born at Montigny-le-Roi, Haute-Marne, Feb. 25, 1842. He first studied theology and afterward astronomy, was attached as a pupil to the Paris observatory from 1858 to 1862, and then became one of the editors of Le Cosmos. In 1865 he was charged with the scientific department of the Siecle, and he also became known as a lecturer, an aeronaut, and an advocate of spiritualism and other peculiar doctrines. He was eventually appointed professor of astronomy at the polytechnic association, president of the meteorological society, and member of several learned bodies. His principal works are: La pluralite des mondes habi-tes (1804; 15th ed., 1869); Les habitants de Vautre monde (2 vols., 1862-3); Les mondes imaginaires et les mondes reels (1805; 8th ed., 1869); Les merveilles celestes (1805); Dieu dans la nature (1866; 6th ed., 1869); and Histoire du ciel (1867). Several of his works have been translated into English, including his Voyages aeriens (in Glaisher's Travels in the Air," 1871), Recits de Vinfini ("Stories of the Infinite," by S. R. Crocker, Boston, 1873), and L'Atmosphere (Paris, 1873), by C. B. Pitman, edited by J. Glaisher (London, 1873).
