9. ARTHUR: A Morocco-born radio presenter who switched to television to host programmes on France 2 and TF1, Arthur prospered after adopting the name of the famous British king. Born Jacques Essebag (you can see why he changed his name), he branched out into theatre with one-man shows and plays before becoming a producer and owner of radio station Oui FM. His fortune was estimated in 2011 at €140 million but he was criticized this year for moving his company to Luxembourg.
