For generations, these industries have literally been household names. In ways almost unimaginable, they have been the lifeblood of the economy. But who are they? And how did they revolutionize and transform the world? . You don’t know them, but you know their names: Milton Hershey, Will Kellogg, Henry Heinz, and the McDonald’s brothers. They are the people behind the food that built the world. Behind the brand names were larger than life characters who built empires that defined far more than the worlds eating habits. They used brains, muscle, blood, sweat, and tears to get to the hearts of millions around the world through their stomach, and along the way they built cities, invented new technologies, and helped win World Wars. They were ruthless, they were thieving, and they were visionaries who changed the landscape of the world forever.
