Microwave-oven-1940s, illustration: united states patent and trademark office a 1947 patent application by raytheon’s percy spencer described the use of microwaves for heating foods, including popcorn.. The 1940’s had many technological advances, but there is one invention that most households use today that was discovered quite by accident. percy spencer invented the microwave oven. he was employed at raytheon in 1941 and working with magnetron. in 1945 he was standing by an operating magnetron and the chocolate bar in his pocket melted., the microwave oven was developed after w.w.ii in order to beat swords into plowshares. perhaps the engineer who is best known for birthing the idea of using microwaves to prepare food was percy spencer, of the raytheon company, located in waltham massachusetts..
