Jacques Cousteau is the most famous and beloved name in the world of deep-sea exploration. Cousteau discovered his passion in 1938, when he first used a pair of goggles to dive off the coast of France. During his time as a French naval officer, he carried out many deep-sea experiments and improved upon early diving equipment. Soon, Cousteau began filming his underwater excursions and offering the world a glimpse below the surface. The documentary television series The Undersea World of Jacques Cousteau
made the man, his work, and his red cap famous throughout the world.
