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. 

Jonnie Boer, Netherlands

Boer started his illustrious career when he was just 24 years old by becoming the head chef of a restaurant that's located in a 16th-century monastery library. Three years later, he bought the restaurant. One year later, he earned his first Michelin star. By 1999, he became the youngest chef in the Netherlands to earn two Michelin stars. One year after that, Boer was knighted.
