Émile Gagnan

Émile Gagnan was a French engineer and inventor best known for developing the modern scuba diving regulator. In the 1940s, he created a device that allowed divers to breathe underwater from compressed air tanks, making scuba diving safer and more practical. His innovation, combined with Jacques Cousteau's expertise, revolutionized underwater exploration by enabling longer and more comfortable dives. Gagnan's work significantly contributed to underwater research, military applications, and recreational diving, and his invention remains the foundation of modern scuba gear.
