Jacques-Yves Cousteau (, also ; ; 11 June 191025 June 1997) was a French naval officer, oceanographer, filmmaker and author. He co-invented the first successful open-circuit self-contained underwater breathing apparatus (SCUBA), called the Aqua-Lung, which assisted him in producing some of the first underwater documentaries.
Cousteau wrote many books describing his undersea explorations. In his first book, The Silent World: A Story of Undersea Discovery and Adventure, Cousteau surmised the existence of the echolocation abilities of porpoises. The book was adapted into an underwater documentary called The Silent World. Co-directed by Cousteau and Louis Malle, it was one of the first films to use underwater cinematography to document the ocean depths in color. The film won the 1956 at the Cannes Film Festival and remained the only documentary to do so until 2004 (when Fahrenheit 9/11 received the award). It was also awarded the Academy Award for Best Documentary in 1957.
From 1966 to 1976, he hosted The Undersea World of Jacques Cousteau, a documentary television series. A second documentary series, The Cousteau Odyssey, ran from 1977 to 1982 on public television stations.
Biography
Early life Cousteau was born on 11 June 1910, in Saint-André-de-Cubzac, Gironde, France, to Daniel Cousteau and Élisabeth Duranthon. He had one brother, Pierre-Antoine. Cousteau completed his preparatory studies at the Collège Stanislas in Paris. In 1930, he entered the École navale and graduated as a gunnery officer. However, an automobile accident, which broke both his arms, cut short his career in naval aviation. The accident forced Cousteau to change his plans to become a naval pilot, so he then indulged his passion for the ocean.
In Toulon, where he was serving on the Condorcet, Cousteau carried out his first underwater experiments, thanks to his friend Philippe Tailliez who in 1936 lent him some Fernez underwater goggles, predecessors of modern swimming goggles. Cousteau also belonged to the information service of the French Navy, and was sent on missions to Shanghai and Japan (1935–1938) and in the USSR (1939).
On 12 July 1937, he married Simone Melchior, his business partner, with whom he had two sons, Jean-Michel (born 1938) and Philippe (1940–1979). His sons took part in the adventures of the Calypso. In 1991, six months after his wife Simone's death from cancer, he married Francine Triplet. They already had a daughter Diane Cousteau (born 1980) and a son, Pierre-Yves Cousteau (born 1982, during Cousteau's marriage to his first wife).
Early 1940s: innovation of modern underwater diving The years of World War II were decisive for the history of diving. After the armistice of 1940, the family of Simone and Jacques-Yves Cousteau took refuge in Megève, where he became a friend of the Ichac family who also lived there. Jacques-Yves Cousteau and Marcel Ichac shared the same desire to reveal to the general public unknown and inaccessible places—for Cousteau the underwater world and for Ichac the high mountains. The two neighbors took the first ex-aequo prize of the Congress of Documentary Film in 1943, for the first French underwater film: Par dix-huit mètres de fond (18 meters deep), made without breathing apparatus the previous year in the Embiez islands in Var, with Philippe Tailliez and Frédéric Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Léon Vèche, an engineer of Arts and Measures at the Naval College.
In 1943, they made the film Épaves (Shipwrecks), in which they used two of the very first Aqua-Lung prototypes. These prototypes were made in Boulogne-Billancourt by the Air Liquide company, following instructions from Cousteau and Émile Gagnan.
Having kept bonds with the English speakers (he spent part of his childhood in the United States and usually spoke English) and with French soldiers in North Africa (under Admiral Lemonnier), Jacques-Yves Cousteau (whose villa "Baobab" at Sanary (Var) was opposite Admiral Darlan's villa "Reine"), helped the French Navy to join again with the Allies; he assembled a commando operation against the Italian espionage services in France, and received several military decorations for his deeds. At that time, he kept his distance from his brother Pierre-Antoine Cousteau, a "pen anti-semite" who edited the collaborationist newspaper Je suis partout (I am everywhere) and who received the death sentence in 1946. However, this was later commuted to a life sentence, and Pierre-Antoine was released in 1954.
During the 1940s, Cousteau is credited with improving the Aqua-Lung design which gave birth to the open-circuit scuba technology used today. According to his first book, The Silent World: A Story of Undersea Discovery and Adventure (1953), Cousteau started diving with Fernez goggles in 1936, and in 1939 used the self-contained underwater breathing apparatus invented in 1926 by Commander Yves le Prieur.The Silent World.

Hamish Hamilton, London. 1953 Cousteau was not satisfied with the length of time he could spend underwater with the Le Prieur apparatus so he improved it to extend underwater duration by adding a demand regulator, invented in 1942 by Émile Gagnan. In 1943 Cousteau tried out the first prototype Aqua-Lung which finally made extended underwater exploration possible. In 1994, Hans Hass publicly claimed priority for the first use of a mobile, self-contained diving apparatus and made this clear to Jacques-Yves Cousteau.Jung, Michael (2026).

Late 1940s: GERS and Élie Monnier In 1946, Cousteau and Tailliez showed the film Épaves ("Shipwrecks") to Admiral Lemonnier, who gave them the responsibility of setting up the GRS (Groupement de Recherches Sous-marines, Underwater Research Group) of the French Navy in Toulon. A little later it became the GERS (Groupe d'Études et de Recherches Sous-Marines, Underwater Studies and Research Group), then the COMISMER (Commandement des Interventions Sous la Mer, Undersea Interventions Command), and finally the CEPHISMER (Centre Expert Plongée Humaine et Intervention Sous la Mer, Expert Centre for Human Diving and Undersea Intervention). In 1947, Chief Petty Officer Maurice Fargues became the first diver to die using an Aqua-Lung, while attempting a new depth record to 120 m with the GERS near Toulon.
In 1948, between missions of mine clearance, underwater exploration and technological and physiological tests, Cousteau undertook a first campaign in the Mediterranean on board the sloop Élie Monnier, According to Sevellec, the Élie Monnier was an old German tugboat originally called Albatros and handed over to France as a war reparation, and then re-baptised in honor of the maritime engineer Élie Monnier who had disappeared while diving at Mers-el-Kébir on the wreck of the battleship Bretagne with Philippe Tailliez, Frédéric Dumas, Jean Alinat and the scenario writer Marcel Ichac. The small team also undertook the exploration of the Roman wreck of Mahdia (Tunisia). It was the first underwater archaeology operation using autonomous diving, opening the way for scientific underwater archaeology. Cousteau and Marcel Ichac brought back from there the Carnets diving film (presented and preceded with the Cannes Film Festival 1951).
Cousteau and the Élie Monnier then took part in the rescue of Professor Jacques Piccard's bathyscaphe, the FNRS-2, during the 1949 expedition to Dakar. Thanks to this rescue, the French Navy was able to reuse the sphere of the bathyscaphe to construct the FNRS-3.
The adventures of this period are told in the two books The Silent World (1953, by Cousteau and Dumas) and Plongées sans câble (1954, by Philippe Tailliez).
1950–1970s In 1949, Cousteau left the French Navy.
In 1950, he founded the French Oceanographic Campaigns (FOC), and leased a ship called Calypso from Thomas Loel Guinness for a symbolic one franc a year. Cousteau refitted the Calypso as a mobile laboratory for field research and as his principal vessel for diving and filming. He also carried out underwater archaeological excavations in the Mediterranean, in particular at Grand-Congloué (1952).
With the publication of his first book in 1953, The Silent World, Cousteau correctly predicted the existence of the echolocation abilities of porpoises. He reported that his research vessel, the Élie Monier, was heading to the Straits of Gibraltar and noticed a group of porpoises following them. Cousteau changed course a few degrees off the optimal course to the center of the strait, and the porpoises followed for a few minutes, then diverged toward mid-channel again. It was evident that they knew where the optimal course lay, even if the humans did not. Cousteau concluded that the cetaceans had something like sonar, which was a relatively new feature on submarines.
In 1954, Cousteau conducted a survey of Abu Dhabi waters on behalf of British Petroleum. Among those accompanying him was Louis Malle who made a black-and-white film of the expedition for the company. Cousteau won the at the Cannes Film Festival in 1956 for The Silent World co-produced with Malle. In 1957, Cousteau took over as leader of the Oceanographic Museum of Monaco. Afterward, with the assistance of Jean Mollard, he made a "diving saucer" SP-350, an experimental underwater vehicle which could reach a depth of 350 meters. The successful experiment was quickly repeated in 1965 with two vehicles which reached 500 meters.
In 1957, he was elected as director of the Oceanographic Museum of Monaco. He directed Précontinent, about the experiments of diving in saturation (long-duration immersion, houses under the sea), and was admitted to the United States National Academy of Sciences.
He was involved in the creation of Confédération Mondiale des Activités Subaquatiques and served as its inaugural president from 1959 to 1973.
Cousteau also took part in inventing the "SP-350 Denise Diving Saucer" in 1959 which was an invention best for exploring the ocean floor, as it allowed one to explore on solid ground.
In October 1960, a large amount of radioactive waste was going to be discarded in the Mediterranean Sea by the Commissariat à l'énergie atomique (CEA). The CEA argued that the dumps were experimental in nature, and that French oceanographers such as Vsevolod Romanovsky had recommended it. Romanovsky and other French scientists, including Louis Fage and Jacques Cousteau, repudiated the claim, saying that Romanovsky had in mind a much smaller amount. The CEA claimed that there was little circulation (and hence little need for concern) at the dump site between Nice and Corsica, but French public opinion sided with the oceanographers rather than with the CEA atomic energy scientists. The CEA chief, Francis Perrin, decided to postpone the dump. Cousteau organized a publicity campaign which in less than two weeks gained wide popular support. The train carrying the waste was stopped by women and children sitting on the railway tracks, and it was sent back to its origin.
In the 1960s, Cousteau was involved with a set of three projects to build underwater "villages"; the projects were named Precontinent I, Precontinent II and Precontinent III. Each ensuing project was aimed at increasing the depth at which people continuously lived under water, and were an attempt at creating an environment in which men could live and work on the seafloor. The projects are best known as Conshelf I (1962), Conshelf II (1963), and Conshelf III (1965). The names "Precontinent", and "Continental Shelf Station" (Conshelf) were used interchangeably by Cousteau.
