Aqua-Lung gained worldwide popularity and commercial success as the first self-contained, opencircuit underwater breathing apparatus. This equipment is also known as the twin-hose diving regulator or demand valve. Aqua-Lung's breathing apparatus works in a similar way to a traditional scuba tank. The regulator is connected and controlled by a demand valve.
Jacques Cousteau
Jacques Cousteau, aqua lung - a fascinating tale in Scuba technology! The invention of the original Aqua-Lung occurred during World War II. Cousteau, who was a French national, invented the underwater breathing apparatus in 1943. His inspiration came from a device perfected by Captain Yves Le Prieur in 1925. Although initially the Aqua-Lung could only perform limited functions, the Germans ordered automobile gas for use on the battlefield. Cousteau took an existing regulator and created the Aqua-Lung. He also invented the autopilot diving system.
After advancing scuba technology, Cousteau went on to discover underwater archeology. He led the first expedition to use self-contained diving equipment and recovered the Roman wreck Mahdia. In the following year, he converted a British minesweeper into an oceanographic research vessel. Unfortunately, he was unable raise the funds to fund the expeditions. He eventually converted his passion for diving into The Silent World which became a popular film.
Aqua-Lung is the most important innovation in scuba diving. It was invented by Jacques Cousteau (in 1959) and has allowed divers freedom of movement under water. Many people have made the Aqua-Lung a standard. Cousteau also helped to develop other tools for oceanographic exploration. Cousteau was the inventor of the first underwater camera in 1959. There's no question that Cousteau's innovations revolutionized the sport of scuba diving.
Emile Gagnan
1945: Emile Gagnan (Jacques Yves Cousteau) and Emile Gaugnan (Emile Gagnan) patent the Aqua-Lung diving regulation. Aire Liquide was a French company that purchased the right to manufacture the regulator. Later, the U.S. sold it. Divers Corporation. It was the most recent development of the French CG45 regulation and was manufactured in Canada. This regulator proved to have great success.
Initially, the Aqua-lung was called Aqua-lung. It was first sold in France in 1946. Then, it was brought to the U.S. in 1952. In 1958, Air Liquide purchased U.S. Aqua Lung America was established in 1958 by Air Liquide, which purchased U.S. Divers. Air Liquide later acquired the company and made it the largest diving company worldwide. Aqua-lung is an integral part of almost all sets of Scuba gear today.
The Aqua-Lung was invented by two Frenchmen: Emile Gagnan and Jacques Cousteau. Both men served as spies during World War II for the French Resistance. Robert Ballard continued his pursuit of the sea after the war. He eventually met Emile Gagnan, a fellow Frenchman who was working for L'Air Liquide. Engineers, they were able to learn high-pressure pneumatic design. Gagnan's ideas evolved into the Aqualung, a fully automated compressed-air diving system.
