The microwave oven did not come about as a result of someone trying to find a better, faster way to cook. During World War II, two scientists invented the magnetron, a tube that produces microwaves. Installing magnetrons in Britain’s radar system, the microwaves were able to spot Nazi warplanes on their way to bomb the British Isles.
In 1946, Dr. Percy Spencer was testing a new vacuum tube called magnetron. Then he was tested many things like popcorn, eggs. Thus, if an egg can be cooked that quickly, why not other foods? Experimentation began...
Dr. Spencer fashioned a metal box with an opening into which he fed microwave power. The energy entering the box was unable to escape, thereby creating a higher density electromagnetic field. When food was placed in the box and microwave energy fed in, the temperature of the food rose very rapidly. Dr. Spencer had invented what was to revolutionize cooking, and form the basis of a multimillion dollar industry, the microwave oven.
After ten years later Spencer patents a "radar range" that cooks with high-frequency radio waves; that same year, the Tappan Stove Co. introduces the first home microwave model.
Earlier, Microwave are very large, heavy and expensive that it was practical only for restaurant and institutional use.

Very interesting site! Good luck with it.
I remember the "radar range' when I was very young.
