	Scubs Diving Equipment
		Emile Gagnan and Jacques Cousteau invented the demand regulator and the autonomous diving suit.
		In 1943, Frenchmen, Emile Gagnan and Jacques Cousteau invented the demand regulator, which adjusted the air pressure automatically, supplying air as the diver needed it.
		Gagnan had started design work on a similar regulator for automobile research, when cooking oil was used to replace gasoline during the war.

	Emile Gagnan - Wikipedia, the free encyclopedia
		Emile Gagnan (born November 1900) was a French engineer and co-inventor (together with Jacques-Yves Cousteau) of the demand-valve used for the first Scuba equipment ("Aqua-Lung") in 1943.
		The demand-valve was designed for regulating gas in gas-generator engines, but was found to be excellent for regulating air-supply under variating pressure conditions.
		Gagnan was born in the French province of Burgoyne in November, 1900, and graduated from technical school in the early 1920's.

		Emile Gagnan (nato nel 1900, morto nel 1979) fu un ingegnere francese e inventore, assieme a Jacques-Yves Cousteau, della valvola di richiamo dell'aqua-lung nel 1943.
		Gagnan nacque in Borgogna (Francia) nel 1900 e si laureÃ² nei primi anni venti.
		Un anno dopo Emile Gagnane e la sua famiglia emigrarono a Montreal, Canada e lÃ¬ iniziÃ² a lavorare per la Canadian Liquid Air Ltd., dove organizzÃ² un laboratorio e continuÃ² a progettare e realizzare un gran numero di tecnologie subacquee, tra cui il prototipo dei moderni erogatori in uso oggi.

	Inventor of the Week: Archive
		Shortly thereafter, in 1943, Jacques-Yves Cousteau and Emile Gagnan invented a system that would revolutionize the world of deep-sea exploration and push diving into the mainstream, allowing people around the world to become exposed to a magical oceanic wilderness they had been unable to experience before.
		Emile Gagnan was born in Burgoyne, France, in 1900.
		In 1947, Gagnan emigrated with his family to Montreal, Canada, where he began working for Canadian Liquid Air Ltd. There he set up a lab and designed and developed a large number of technologies integral to the evolution of modern SCUBA equipment.

	Cousteau, Jacques
		He joined French engineer Émile Gagnan in designing a breathing apparatus that would appropriately regulate air pressure at varying water depths.
		In 1943, after several experiments, Cousteau and Gagnan finally invented the demand regulator, solving the problem of equalizing air pressure in the lungs with the water pressure acting upon the diver's body.
		The complete set of equipment was called the "aqualung"; and would enable divers to dive deeper for longer periods of time.

		Previous to this, divers needed a constantly free-flowing supply of air - the high volume of which required that the air be supplied from above with a compressor.

		One of the first significant developments in the evolution of modern dive technology was the Aqualung, the first open-circuit scuba (self-contained underwater breathing apparatus) diving system.
		It was developed by Emile Gagnan and Jacques Cousteau in 1942 and consisted of a high-pressure diving cylinder and a diving regulator that supplied the diver with breathing gas at ambient pressure.
		Today, as diving technology and materials become more and more sophisticated, Jean-Michel Cousteau, like his father, is at the cutting edge of discovering, designing, developing and experimenting with models and designs that have the potential to take divers deeper, longer.
