Jacques-Yves Cousteau (1910 - 1997)
"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."
"When one man, for whatever reason, has the opportunity to lead an extraordinary life, he has no right to keep it to himself"
- Jacques Yves Cousteau
Along with Carl Sagan, one of the people that incited my love for science since I was a kid.
