The self-contained amphibious underwater Calypso 35mm film camera was conceived by the marine explorer Jacques-Yves Cousteau (1910—1997), designed by Jean de Wouters and manufactured by Atoms in France. It was distributed by La Spirotechnique in Paris from 1960 to 1962. The camera operates down to 200 feet / 60meter below sea level. The Calypso was sometimes advertised as the “CALYPSO-PHOT”. Nikon took over production and sold it as the Nikonos, which subsequently became a well-known series of underwater cameras.
