Jacques Cousteau, the legendary oceanographer captured the imagination of millions around the world with his documentaries on underwater life and the beauty of the seas.
In 1963, using a yellow submarine, he docked with an underwater research centre where five aquanauts lived for an entire month. The story made newspaper headlines all over the world and Cousteau's fame was ensured.
Public imagination has since been driven by space exploration and travel with little attention being paid to the oceans. Cousteau's grandson Fabien Cousteau is planning to change all that by envisioning the world's largest underwater research station, named after the sea god Proteus.
