Marie DuBois is a fictional character who appeared in the Hogan's Heroes episode, The Scientist. She was played by Jayne Massey. Marie is first mentioned in the episode, when her father, Henry DuBois, tells LeBeau the reason why he is presently, although very reluctantly, working for the Germans: they are holding her as a hostage at the hotel in town and he doesn't want any harm to come to her. He then informs LeBeau that they were originally captured by the Germans after the Fall of France, and that he has so far done everything he could to actually keep the Germans from exploiting his knowledge of synthetic fuels.
