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 to a demand valve, which regulates the flow of air in and out of the lungs.
Jacques Cousteau
Jacques Cousteau, aqua lung - a fascinating tale in Scuba technology! The original Aqua-Lung was invented during World War II. Cousteau, a French national, developed the underwater breathing apparatus in 1943. He was inspired by a 1925 invention by Captain Yves Le Prieur. Although initially the Aqua-Lung could only perform limited functions, the Germans ordered automobile gas for use on the battlefield. Cousteau, using an existing regulator, developed the Aqua lung and invented the autonomous diving device.
Cousteau became an expert in scuba diving technology and went on to discover underwater archeology. He led the first expedition to use self-contained diving equipment and recovered the Roman wreck Mahdia. He also converted a British mining vessel into an oceanographic research vessel by using a British minesweeper. 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 has been the most important innovation in diving. It was developed by Jacques Cousteau, in 1959. Since then it has allowed divers to freely swim under water. Many people have made the Aqua-Lung a standard. Cousteau also helped to develop other tools for oceanographic exploration. In fact, the first underwater camera was also invented by Cousteau in 1959. Cousteau's inventions revolutionized scuba dive.
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. It was later sold to the U.S. Divers Corporation. It was the latest design of the French CG45 regulator. It was assembled in Canada. This regulator proved to be extremely successful.
Initially, the Aqualung was called Aqua-lung. The first Aqua-lung sold in France was in 1946. In 1952, it was imported to the U.S. In 1958, Air Liquide purchased U.S. The company was renamed Aqua Lung America after it acquired U.S. Divers. Air Liquide later acquired the company and made it the largest diving company worldwide. Aqua-lung today is a major component in nearly all Scuba Gear sets.
Emile Gagnan (France) and Jacques Cousteau (France) invented the Aqua-Lung. Both men were spy for the French Resistance during World War II. Robert Ballard maintained his love for the sea even after the war. Emile Gagnan, who was also a Frenchman working for L'Air Liquide, became his friend. As engineers, they learned to use high-pressure pneumatic design. Gagnan’s idea was realized into an fully-automated, compressed-air system for scuba diving called Aqua-Lung.
