Simone Melchior Cousteau (19 January 1919 – 1 December 1990) was the wife and business partner of undersea explorer Jacques-Yves Cousteau. The first woman scuba diver and aquanaut, Simone was at Jacques's side during his major underwater accomplishments. She led him to the men and money who would build his scuba invention, she helped buy their beloved Calypso, saved the ship during a storm, and made sure each exploration achieved its objective.
