Aqua-Lung was the world's first self contained, open circuit underwater breathing apparatus. It gained global fame and commercial success. This equipment is commonly known as the twin-hose regulator or demand valve. Aqua-Lung breathing apparatus functions in a manner similar 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 and the aqua lung - a remarkable story in Scuba tech! The invention of Aqua-Lung, the first underwater breathing apparatus, was made during World War II. Cousteau, who was a French national, invented the underwater breathing apparatus in 1943. His inspiration was Captain Yves Le Prieur's 1925 device. Although the Aqua-Lung was initially limited in functionality, the Germans eventually requisitioned gasoline to be used on the battlefield. Cousteau modified an existing regulator to develop the Aqualung and later invented the autonomous diving system.
After advancing scuba technology, Cousteau went on to discover underwater archeology. 1946 was the year Cousteau led the first self-contained diving operation and recovered the Roman shipwreck Mahdia. The following year, he transformed a British minesweeper to an oceanographic research vessel. He struggled to raise the money for the expeditions. His passion for diving eventually led him to create The Silent World, a book that became a success.
Aqua-Lung is the most important innovation in scuba diving. It was developed by Jacques Cousteau, in 1959. Since then it has allowed divers to freely swim under water. The Aqua-Lung has been a common tool for many, and Cousteau contributed many other tools to oceanographic exploration. Cousteau invented the first underwater cam in 1959. Cousteau’s innovations revolutionized scuba diving.
Emile Gagnan
In 1945, Emile Gagnan and Jacques Yves Cousteau patented their Aqua-Lung diving regulator. Aire Liquide (a French company) purchased the rights for the manufacture of the regulator. It was later sold by the U.S. Divers Corporation. It was the latest design of the French CG45 regulator. It was assembled in Canada. This regulator was extremely successful.
The Aqua-lung was initially called the Aqua-lung and was first sold in France in 1946. The Aqua-lung was later brought to America in 1952. In 1958, Air Liquide purchased U.S. The company was renamed Aqua Lung America after it acquired U.S. Divers. Air Liquide eventually made the company a division and it is now the world's largest diving company. Aqua-lung today is a major component in nearly all Scuba Gear sets.
Emile Gaugnan and Jacques Cousteau were the two Frenchmen who invented Aqua-Lung. Both men were spy for the French Resistance during World War II. Robert Ballard kept his interest in the ocean even after the war. Emile Gagnan became his partner in crime, and he was working at L'Air Liquide as a Frenchman. They both learned how to use high pressure pneumatic design while engineers. Gagnan's ideas evolved into the Aqualung, a fully automated compressed-air diving system.
