Jacques-Yves Cousteau, the amiable Frenchman who is known for his endless thirst for exploration, unbridled curiosity, and unique story-telling, arguably did more to popularize scuba diving and shepherd its development than any of his predecessors—and many of his successors. Often referred to as the father of scuba diving, Cousteau is a true diving legend. Cousteau teamed up with Emile Gagnan in 1942. By 1943, they had designed and tested a scuba set with a double-hose demand regulator that could be mounted onto air tanks holding up to 200 atmospheres, allowing dive times longer than an hour at significant depths. They called it the Aqua-Lung.
