Louis Le Duff is a French entrepreneur and the founder and CEO of Groupe Le Duff, the restaurant and bakery group behind the Brioche Dorée chain. He was born in 1945 or 1946 and grew up in Brittany, where he went to school at the Lycée de la Croix-Rouge in Brest.

He is unusually well educated for a restaurant founder. He earned a bachelor's degree from the ESSCA business school in Angers, an MBA from the Université de Sherbrooke in Canada and a PhD in management sciences from the University of Rennes. Before building his company he taught at the Rouen Business School and lectured at the University of Rennes 1.

In the summer of 1970, while studying at Columbia University in New York, he worked night shifts at a French crêperie, an early taste of the food business. Le Duff is married with two children and lives in Paris.

How Louis Le Duff made his money

His first venture came while he was studying for his MBA in Canada, when he opened a combined restaurant and bakery at a Quebec ski resort. In 1976 he brought the idea home and opened the first Brioche Dorée bakery in Brest, Brittany, reportedly with just $2,000. The quick service bakery café format caught on, and the chain now has 1,310 locations in 80 countries.

Groupe Le Duff grew into a family of brands with more than 1,000 bakery and restaurant locations, including the La Madeleine French café chain in the United States and the Del Arte chain in France. Its biggest business is Bridor, which makes high quality breads and pastries for hotels, restaurants and caterers in more than 100 countries. He also owns frozen food maker Gourming, and he owned Bruegger's Bagels from 2011 until 2017, when he sold it to Caribou Coffee Company.
