Francine Cousteau (née Triplet; born 1946) is the president of the non-profit organization Cousteau Society, and is the widow of oceanographer Jacques-Yves Cousteau. She is the mother of Jacques Cousteau's third and fourth children, Diane and Pierre-Yves.
After Jacques Cousteau's death, Francine became involved in legal battles with family members regarding her husband's financial and spiritual legacies,[1] as well as the salvage and use of RV Calypso whose fixing and refurbishing has never materialized since its sinking and recovery in bad condition in 1996.[2]
