Aqua-Lung, which was the first self-contained open-circuit underwater breathing system, has gained international fame and commercial success. This class of equipment is now commonly referred to as the demand valve or twin-hose diving regulator. The basic concept of Aqua-Lung breathing apparatus is similar to that of 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 aqua lung - a fascinating story in Scuba technology! The original Aqua-Lung was invented during World War II. Cousteau was a French national who developed the underwater breathing device in 1943. His inspiration was Captain Yves Le Prieur's 1925 device. The Aqua-Lung had limited functionality at first, but the Germans demanded that automobile gas be requisitioned to use on the battlefield. Cousteau, using an existing regulator, developed the Aqua lung and invented the autonomous diving device.
Cousteau was instrumental in the development of scuba technology and discovered underwater archeology. He led the first self-contained diving expedition in 1946 and recovered the Roman shipwreck Mahdia. The following year, he transformed a British minesweeper to an oceanographic research vessel. 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 has been the most important innovation in diving. It was designed by Jacques Cousteau in 1959 and allows divers to safely and comfortably swim below water. The Aqua lung has been a popular tool, and Cousteau is responsible for the creation of many other tools that allow for oceanographic exploration. Cousteau also invent the first underwater camera, which was invented in 1959. There's no question that Cousteau's innovations revolutionized the sport of scuba diving.
Emile Gagnan
In 1945, Emile Gagnan and Jacques Yves Cousteau patented their Aqua-Lung diving regulator. Aire Liquide in France purchased the rights and manufactured the regulator. Later, the U.S. purchased it. 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. It was then brought to the United States in 1952. In 1958, Air Liquide purchased U.S. Air Liquide purchased U.S. Divers in 1958 and changed its name to Aqua Lung America. Air Liquide later acquired the company and made it the largest diving company worldwide. Today, the Aqua-lung is a major component of nearly every set of Scuba gear worldwide.
Emile Gagnan (France) and Jacques Cousteau (France) invented the Aqua-Lung. Both men served as spies during World War II for the French Resistance. 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 original idea evolved into the Aqua-Lung, a fully-automated compressed air scuba system.
