CELEBRATING 80 YEARS
FIRST TO DIVE
80 years ago we cut the cord. When Jacques Cousteau and Emile Gagnan invented the Aqua Lung, history was forever changed. This single piece of equipment launched decades of innovation, and empowered discovery by making the underwater world more accessible. Inventing the sport we now know as Scuba diving, Cousteau and Gagnan became pioneers of an aquatic revolution.
French naval officer Jacques-Yves Cousteau and Air Liquide engineer Emile Gagnan develop an autonomous diving system with a demand regulator, the scaphandre autonome. It would soon be called "Aqua-Lung," after Cousteau coined the word for English-speaking countries.
