Microwave Oven Patent PictureJanuary 24, 1950

The original microwave oven patent was issued to Percy LeBaron Spencer under the title “Method of Treating Foodstuffs.” Five years earlier, Spencer accidentally discovered that microwave energy could heat food when a chocolate bar in his pocket melted while he was experimenting with a microwave tube. Microwave tubes were originally designed for RADAR systems.
