The story of the microwave invention is fascinating because the inventor Percy LeBaron Spencer never intended to invent this food warming device. He was a scientist working with microwave-producing Megatron tubes originally for a radar project and observed that the candy bar in his pocket had melted. Then next, he popped popcorn kernels with this device and exploded an egg in his lab. Spencer and the staff at Raytheon lab forgot about the radar project and started working to develop a microwave machine for cooking. On October 8, 1945, he filed a patent for his six feet tall and weighed 670 pounds invention with the title “Method of Treating Foodstuffs.” The US patent office awarded the patent on January 24, 1950.
