Pierre Gagnaire, Paris

There was a hard, dark side to my family,’ begins the chef whose face is now synonymous with a smile. ‘[My father] was an introverted man, not at all expressive. He was orphaned and had been brought up by a strict and authoritative grandmother.’ Jean-Claude Gagnaire, an Apinac native, ran a one-starred restaurant in Saint-Étienne. ‘The motto in my family was do your duty…I was the eldest in the family of four and I knew what I had to do.’
