Although  raised a strict Catholic  Bettencourt Meyers  married the grandson of a rabbi killed in Aushwitz â all the more notable given that L'Oreal's founder  EugÃ¨ne Schueller  was a known Nazi sympathizer .
 Bettencourt Meyers  is arguably best known for bringing legal action against  her  mother  after the elder Bettencourt began giving away millions in assets and insurance to society photographer FranÃ§ois-Marie Banier  with whom she'd struck up an unusual friendship.
