The quest for stereoscopic movement : was the first film ever in 3-D?

Abstract

Histories of the cinema mention the Lumière brothers and sometimes Louis Le Prince as the precursors of the moving pictures but they usually forget the important part played by Antoine Claudet, Louis Jules Duboscq, Charles Wheatstone and Joseph Plateau. Barely a year after the introduction of the lenticular stereoscope, these polymaths managed to create what can not only be considered as the first "movie" ever but also happens to be in 3-D!
