Jacques-Yves Cousteau (1910–1997) was a French naval officer, oceanographer, and filmmaker who did more than almost anyone to bring the deep sea to a general audience. With the engineer Émile Gagnan he co-invented the Aqua-Lung in 1943, the first widely used open-circuit scuba gear, and he spent the next half century filming the ocean from the deck of the research ship Calypso.
Jacques-Yves Cousteau was born on June 11, 1910, in Saint-André-de-Cubzac, in the Gironde region of southwestern France. He was a restless child who took early to swimming and to machines, cameras above all. After attending the Collège Stanislas in Paris, he entered the École navale, the French naval academy, and graduated in 1930. He first meant to become a naval aviator, but a car accident that broke both of his arms ended that ambition. During his recovery he swam in the Mediterranean to rebuild his strength, and in 1936 he first tried a pair of underwater goggles off Toulon. That clear look beneath the surface, he later said, set the course of his life.
Cousteau served as a gunnery officer in the French Navy through the Second World War. The central problem of early diving was air supply: existing gear tied a diver to a surface pump or delivered air at an awkward, fixed rate. Working with the engineer Émile Gagnan in occupied France, Cousteau helped adapt a demand regulator so that a diver breathing from a compressed-air tank drew air only when he inhaled, at the surrounding water pressure. The result, first tested in 1943, was the Aqua-Lung, the open-circuit scuba that let a swimmer move freely and stay down far longer than before.
In 1950 Cousteau acquired Calypso, a former Royal Navy minesweeper, and refitted her as a floating laboratory and film platform; a British backer leased the ship to him for a symbolic one franc a year. Calypso carried him on decades of expeditions, from archaeological dives to marine-life surveys to a 1977 study of Mediterranean pollution.
Cousteau turned those voyages into some of the most watched nature films ever made. His book The Silent World, written with Frédéric Dumas in 1953, became the 1956 film of the same name, which he co-directed with the young Louis Malle. It won the Palme d'Or at the Cannes Film Festival and, the following year, the Academy Award for best documentary. From 1968 to 1976 the American television series The Undersea World of Jacques Cousteau, narrated in its ABC edition by Rod Serling, carried his red-capped image and his ship into living rooms around the world.
Over his career Cousteau made more than 120 television documentaries and wrote or co-wrote some 50 books, and his fame gave weight to a growing concern for the sea. In 1973 he founded The Cousteau Society, a nonprofit devoted to protecting marine life, and he campaigned publicly against ocean pollution and the dumping of radioactive waste in the Mediterranean. He received the United States Presidential Medal of Freedom in 1985 and was elected to the Académie française in 1988. Cousteau died of a heart attack in Paris on June 25, 1997, at the age of 87. The Cousteau Society continues his conservation work, and the vocabulary he helped make familiar, from scuba diving to the fragile health of the oceans, remains in everyday use.
Cousteau's story runs together an invention, a ship, and a long run of films, and quick summaries tend to fold them into one blur. Keeping his record here holds the dates, the named collaborators, and the specific films and honors in one checkable place.
