Are you a fan of Food Network's "Chopped" or Bravo's "Top Chef Masters"? If so, then you're probably familiar with culinary force Marcus Samuelsson. Learn more about his past in his memoir, "Yes, Chef." Samuelsson was born in Ethiopia and lost his mother when he was 3. A Swedish family adopted Samuelsson and his sister and taught him about food and cooking. He attended culinary school and went onto work in kitchens in France and New York City. Next came reality shows, White House dinners and Red Rooster Harlem, Samuelsson's restaurant that serves comfort food from his African and European roots.
