Yves Carcelle, the longtime director of LVMH's fashion and leathergoods division, is transferring his responsibilities as president and chief executive of its crown jewel, Louis Vuitton, to Jordi Constans at the end of 2012. The 47-year-old manager comes from the big Danone group, where he ran its fresh dairy products division and sat on its executive board. LVMH says Constans will spend next year familiarizing himself with the group before taking his place at Vuitton. Carcelle will continue to be involved as president of the Louis Vuitton Foundation, a museum that is due to open in 2013. He will remain a member of LVMH's executive committee, assuming strategic roles on the side of Bernard Arnault, chairman of the group. Separately, Jean-Marc Gallot, 46, is coming back to Vuitton from Ruinart, the French brand of champagne, as deputy general manager. After running Ferragamo Usa, he joined LVMH in 2003 as president of Louis Vuitton North America, and then ran its European operations between 2006 and 2009. Prior to Ferragamo, he worked for Cartier and Christofle.
