Percy LeBaron Spencer is regarded as the inventor of the microwave oven. Spencer worked as an engineer with the Raytheon company, which was a company that developed defence and industrial equipment. The story goes that the concept of the microwave was discovered by accident while Spencer was experimenting with and testing a magnetron (diode vacuum tube).
The magnetron, which had been invented during WWII at Manchester University, produced microwaves of such high frequency and power that it was invaluable in directing allied aircraft to intercept German Luftwaffe raiders during the battle of Britain.
The magnetron was passed to Raytheon in the USA for further development. During testing, Dr Spencer reached into his pocket for his chocolate bar and discovered it had completely melted. He noted the connection between the melted chocolate and the heat-producing magnetron, and tested his theory on a bag of unpopped corn kernels, which then popped. In further testing, he placed an egg in front of the magnetron, and the egg exploded.
For this reason, Spencer is credited with discovering one of the critical components of the microwave oven. Further modifications of the microwave oven developed out of his observations, and by 1947 Raytheon had perfected a commercial microwave oven. It was a large unit about the size of a tall cupboard and remained large until the Apollo 11 astronauts returned to Earth and were immediately quarantined in a sealed caravan in case they had brought Moon bacteria back to Earth. They cooked their meals on one of the first counter top Microwave ovens ever made.

The first magnetron was invented by Randall and Boot at Bournemouth University in 1940. Due to the exigencies of war, this invention like many others was suppressed from public knowledge at the time.
