Who invented the microwave oven?
This invention is credited to Percy L. Spencer, a World War II hero and electronics genius. One day he was in a laboratory and stopped in front of a magnetron, the power tube that drives a radar set. He then noticed that the chocolate bar in his pocket had melted in the tube’s presence. He experimented with unpopped popcorn, and sure enough the magnetron β€œheated” the corn to popping, spurring his company, Raytheon, to develop the first microwave oven. It reportedly weighed 750 pounds, was more than 5 feet tall, and didn’t work all that well. It took decades to perfect the microwave oven into the useful household appliance we know today.
