Description Jacques-Yves Cousteau was a French naval officer, explorer, ecologist, filmmaker, scientist, photographer 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 Acadmie franaise. In October 1960, a large amount of radioactive waste was going to be discarded in the sea by the European Atomic Energy Community. Cousteau organized a publicity campaign which in less than two weeks gained wide popular support. The train carrying the waste was stopped by women and children sitting on the railway, and it was sent back to its origin. The risk was avoided. During this, a French government man had said falsely to a newspaper that Cousteau had approved the dump; Cousteau managed to get the newspaper to issue a correction.
