French national Françoise Bettencourt Meyers, the L'Oréal heiress and the first woman to accumulate a $100 billion fortune, stands as a testament to a legacy intertwined with beauty, wealth, and familial intrigue. Her wealth jumped to $100.1 billion this week, according to the Bloomberg Billionaires Index as shares of L’Oréal SA, the beauty products empire founded by her grandfather, rose to a record high, with the stock set for its best year since 1998. She’s the 12th-richest person in the world, just behind Mexico’s Carlos Slim.
