(3456) Etiennemarey Main-belt Asteroid
Discovered on 5 September 1985 by H. Debehogne at La Silla.
In 1890 the French physiologist Etienne-Jules Marey (1830-1904) made the first use of celluloid roll film in movie photography. The name is derived from a suggestion by T. Wullin, who, as part of a minor-planet naming competition on the BBC Radio 4 program Word of Mouth, noted that 3456 = FILM on the keys of a telephone.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
