Jacques Cousteau was the most famous undersea explorer in the world, known by his dozens of books and films from the 1950s until his death in 1997. The co-inventor of the aqualung (an underwater breathing apparatus) in 1943, Cousteau also pioneered techniques in underwater photography and explored the oceans of the world aboard his vessel Calypso. His filmmaking career included three Oscars, frequent television specials and the series, The Undersea World of Jacques Cousteau (1966). In his later years Cousteau devoted himself to educating the public on environmental issues, and working with the Cousteau Foundation, founded in 1973 to further marine research and exploration.
