The evolution of SCUBA diving spans over two centuries. It began in 1825 with inventors creating early air supply systems for divers. Key advancements included the Aerophore, which had a regulator for air control in 1865, and the invention of the aqualung by Jacques-Yves Cousteau and Emile Gagnan in 1943, which revolutionized diving. The progression from simple devices to modern equipment showcases human innovation in exploring the underwater world.
