#15 Liliane Bettencourt & family-Net Worth $33.6 Billion $168 M | -0.5% As of 4/12/2014

L'Oreal's grand dame Liliane Bettencourt is no longer the world's richest woman, though she grew wealthier this year thanks to the French cosmetics giant's stock price, up 9% since 2013. Bettencourt is no longer involved in running the company her father founded after a 2011 legal battle with daughter Françoise Bettencourt Meyers proved Liliane was unfit to manage her affairs. The elderly widow, who suffers from dementia, was replaced on the company's board by her 25-year-old grandson Jean-Victor Meyers in February 2012. The Bettencourt family is set to strengthen its hold on the L'Oreal empire in 2014 thanks to Swiss consumer goods giant Nestle's planned sale of its 8% stake. That will raise the family's holdings to 33%.
