French physicist and astronomer, Henri Chretien, invents the anamorphic objective lens, which contracts images vertically perimitting wide-screen movies. It is ignored until the 1950s, when his invention is patented as Cinemascope.
Georges-Michel Coissac publishes L’histoire du cinematographe/History of Cinema, the first history of filmmaking.
