Aqua-Lung was the world's first self contained, open circuit underwater breathing apparatus. It gained global fame and commercial success. This equipment is often referred to as the "demand valve" or "twin-hose diving regulator". Aqua-Lung's breathing apparatus works in a similar way to a traditional scuba tank. The regulator is connected via a demand valle, which regulates the flow air through the lungs.
Jacques Cousteau
Jacques Cousteau and the aqua lung - a remarkable story in Scuba tech! The invention of the original Aqua-Lung occurred during World War II. Cousteau, a French national, developed the underwater breathing apparatus in 1943. Captain Yves Le Prieur, a 1925 inventor, was his inspiration. While the Aqua-Lung was initially a limited-functioning device, the Germans requisitioned automobile gas to use on the battlefield. Cousteau adapted an existing regulator to create the Aqua-Lung, and then invented the autonomous diving system.
Cousteau was instrumental in the development of scuba technology and discovered underwater archeology. He led the first expedition to use self-contained diving equipment and recovered the Roman wreck Mahdia. He converted an old British minesweeper into a research vessel for oceanographic studies the next year. Unfortunately, he struggled to raise the funds for the expeditions and he eventually turned his passion for diving into a book called The Silent World, which became a successful 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 invented the first underwater cam in 1959. Cousteau's innovations have revolutionized scuba diving.
Emile Gagnan
In 1945, Emile Gagagnan and Jacques Yves Cousteau patented the Aqua-Lung diving regulator. Aire Liquide was a French company that purchased the right to manufacture the regulator. It was later sold by the U.S. Divers Corporation. This regulator was the latest innovation of the French CG45 regulator, and it was made in Canada. This regulator proved to be extremely popular.
Initially, the Aqua-lung was called Aqua-lung. It was first sold in France in 1946. The Aqua-lung was then introduced to the U.S.A in 1952. In 1958, Air Liquide purchased U.S. Divers and changed the company's name to Aqua Lung America. Air Liquide later acquired the company and made it the largest diving company worldwide. Aqua-lung has become a major component of almost every set Scuba gear.
Emile Gagnan (France) and Jacques Cousteau (France) invented the Aqua-Lung. Both men were spymen for the French Resistance during World War II. Robert Ballard pursued his passion for the sea after the war. Emile Gagnan was a Frenchman who worked for L'Air Liquide. He eventually met Emile. They learned high-pressure pneumatic design as engineers. Gagnan's concept evolved into an automated compressed-air scuba diving system called the Aqua-Lung.
