Flammarion, Camille (kämēˈyə flämäryôNˈ) [key], 1842–1925, French astronomer and author. He served for some years at the Paris Observatory and the Bureau of Longitudes, and in 1883 he set up a private observatory at Juvisy (near Paris) and continued his studies, especially of double and multiple stars and of the moon and Mars. He is noted chiefly as the author of popular books on astronomy, including Popular Astronomy (1880, tr. 1907) and The Atmosphere (1871, tr. 1873). His later studies were on psychical research, on which he wrote many works, among them Death and Its Mystery (3 vol., 1920–21; tr. 1921–23).
