One of the most influential men of the twentieth century, Jacques Cousteau was an eco-emissary whose own life of derring-do brought him fame and the means to proselytize his cause. Ecologist, adventurer, celebrity, businessman—Cousteau was a brilliant and complex individual, and Madsen's biography captures him in style. Madsen, who knew the Cousteau family for over two decades, interviewed Cousteau personally for this book.
