Bernard Arnault, (born March 5, 1949, Roubaix, France), French businessman best known as the chairman and CEO of the French conglomerate LVMH Moët Hennessy Louis Vuitton SA, the largest luxury-products company in the world.Arnault graduated from the École Polytechnique in Paris with a degree in engineering. In 1971 he took control of his father’s construction firm Ferret-Savinel. Eight years later he changed the company’s name to Férinel Inc. and shifted its focus to real estate.With $15 million of his own money, Arnault, together with Antoine Bernheim, a managing partner of the French bank Lazard Frères and Co., raised the $80 million necessary to purchase Boussac Saint-Frères, a bankrupt textile company that owned the fashion house of Christian Dior. Then, in 1987, Arnault was invited to invest in LVMH by the company’s chairman, Henri Racamier. Investing through a joint venture with Guinness PLC, Arnault ousted Racamier in 1990 and started to sweep a slew of fashion companies into the LVMH Christian Lacroix, Givenchy, and Kenzo; the leather goods companies Loewe, Céline, and Berluti; the jeweler Fred Joailler; the DFS group (the world’s biggest duty-free chain); and the beauty retailer Sephora.
