Bettencourt, whose net worth was estimated
She was the daughter of Eugène Schueller, a chemist and one-time Nazi sympathiser who made a fortune as the inventor of modern hair dye and founder of L’Oréal. Her mother died when she was five, leaving her alone with Schueller whose company she inherited.
Bettencourt hit the headlines in 2007 when members of her entourage were charged with exploiting her failing mental health – leading to a vast inquiry that threatened to engulf the then-president Nicolas Sarkozy.
