The French explorer Jacques – Yves Cousteau was born on June 11, 1910. He invented the Aqualung diving apparatus, along with Emile Gagnan. Cousteau was introduced to Gagnan by his father, who worked for a company in Paris, specialising in compressed gases. Gagnan, an engineer, had been working on valve designs.

Before the aqualung, divers used a diving suit and a helmet, which were heavy and required a hose that was attached to an air compressor on the land or a boat. This had been in use for the last 100 years before Cousteau and Gagnan invented the Aqualung.

The Aqualung uses a regulator or a demand valve. It allows the person to breathe in and out through the same mouthpiece. The regulator is connected to a tank of compressed gas, which is attached to the vest worn by the diver. This equipment helps people to go deep down under the water and stay put for a longer time. It has made underwater study and exploration of marine life easy.

Today we know Aqualung by the name of SCUBA, which is an acronym for Self-Contained Underwater Breathing Apparatus.

Apart from being an explorer, Jacques Cousteau has written many books, made films on marine conservation. His TV show, ‘The Undersea World of Jacques Cousteau’ brought the oceans into the people’s living room.
