Nicolas Camille Flammarion (26 February 1842—3 June 1925) was a French astronomer and author. He was a prolific author of more than fifty titles, including popular science works about astronomy, several notable early science fiction novels, and several works about Spiritism and related topics. At the age of nineteen, he published his first work, La Pluralité des Mondes Habités, which caught the public taste and was at once translated into several languages. From 1862 to 1866 he was attached to the Bureau des Longitudes. He also published the magazine L'Astronomie, starting in 1882. He maintained a private observatory at Juvisy-sur-Orge, France.
The asteroid (107) Camilla, discovered by N. R. Pogson on November 17, 1868, was named after Camilla, Queen of the Volsci in Roman mythology... but it is believed by some that Camilla also derives from M. Flammarion's first name.
M. Flammarion was elected an honorary fellow of the Astronomical Society of Toronto on 1901-09-03. At the same meeting, president G.E. Lumsden announced that it was proposed to name a point in Lake Rosseau in the Muskoka region in honor of M. Flammarion, and the dedication has stuck.
