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 documentary adaptation of the book , '' The Silent World '' , 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 ''
