Larry Ellison vs. Bernard Arnault & family

Ellison never finished college. He started out building databases for the CIA. Daughter Megan has financed films such as Zero Dark Thirty and American Hustle; son David produced mainstream movies like The Terminator and Mission: Impossible".

Arnault apparently wooed his wife, Helene Mercier, a concert pianist, by playing Chopin and other classical composers on the piano. Arnault and LVMH own a 40% stake in private equity firm L Catterton, which has $30 billion in assets, including investments in Birkenstock and Equinox.
