Born into a farming family in Lyon, France, Daniel Boulud knew at 14 that he wanted to be a chef. He trained as an apprentice, rose through the ranks of his home country’s best restaurants, did a stint in Copenhagen, and then emigrated to New York City, where he was hired at the famed Le Cirque. In 1993 he struck out on his own and opened Daniel, spawning a culinary empire that now includes 16 ventures.
