A Brief History of Microwave Ovens | The Henry Ford's Innovation Nation

Mo Rocca meets with Curator of Domestic Life, Jeanie Miller, to talk about the history of microwave ovens. Microwave technology was discovered by accident by engineer Percy Spencer. It came out of the research being done on radar during World War II. After Percy Spencer discovered a melted chocolate bar in his pocket when walking by a magnetron — a device that produced electromagnetic waves — he realized the potential of using tiny electromagnetic waves to heat food. Microwave ovens gained popularity in the 1970s, becoming all but standard in American kitchens by the mid-1980s. These new appliances cooked food differently than conventional stovetop or oven methods, which worked by surrounding food with heat. In a microwave oven, electromagnetic waves caused food molecules to vibrate, creating heat that transferred from the outside to the center of the food. Today, microwave ovens have entered the digital era, using computer chips to expand the types of cooking and defrosting that a microwave can do.
