Jacques-Yves Cousteau

Jacques-Yves Cousteau, (, also UK: , French: [ʒak iv kusto]; 11 June 1910 – 25 June 1997) was a French naval officer, explorer, conservationist, filmmaker, innovator, scientist, photographer, author and researcher who studied the sea and all forms of life in water. He co-developed the Aqua-Lung, pioneered marine conservation and was a member of the Académie Française.
Cousteau described his underwater world research in a series of books, perhaps the most successful being his first book, The Silent World: A Story of Undersea Discovery and Adventure, published in 1953. Cousteau also directed films, most notably The Silent World, the documentary adaptation of his book, which won a Palme d’or at the 1956 Cannes Film Festival. He remained the only person to win a Palme d’Or for a documentary film until Michael Moore won the award in 2004 for Fahrenheit 9/11.
