Gagnan's boss, Henri Melchior, knew that his son-in-law Jacques-Yves Cousteau was looking for an automatic demand regulator to increase the useful endurance of the underwater breathing apparatus invented by Commander Yves le Prieur, [8] so he introduced Cousteau to Gagnan in December 1942. On Cousteau's initiative, the Gagnan regulator was ...

Jacques-Yves Cousteau had one of those faces that seemed to come from an earlier time — before the world wars, maybe even before the 20th century. It was a face so thin and tapered yet open, so ...
In 1942, during the German occupation of France, Jacques-Yves Cousteau and Émile Gagnan designed the first successful and safe open-circuit scuba, known as the Aqua-Lung. Their system combined an improved demand regulator with high-pressure air tanks. [20] This was patented in 1945.
The "Aqua-Lung" regulator was created by Jacques-Yves Cousteau and Émile Gagnan in 1943. [5]In 1946, the company known as La Spirotechnique (now Aqua Lung International) was established by both men together with Jean Delorme, CEO of Air Liquide, as a division of Air Liquide to sell the Aqua-Lung regulators.
