Dan Barber, United States

Barber is both a culinary genius and an arborist innovator. He isn't as famous for his cooking as he is for his establishment of new crossbred fruits and vegetables. He led the farm-to-table era of cooking in the United States and was appointed to the President's Council on Physical Fitness, Sports, and Nutrition by President Obama during his time in the White House. Barber doesn't have any Michelin stars, but he has a dozen or so James Beard awards.
