Who invented the microwave ovens?

No one discovered microwave ovens. They were first used in 1837 or so when a high school dropout discovered that microwaves emitted heat (or something). He noticed this as he reached into his pocket for his chocolate bar, only to find it had melted. He had been working in a lab full of microwaves (the radiation type, not the oven). The next time, he brought an egg and some popcorn. The egg exploded, having being cooked from the inside. Later, popcorn was popping everywhere. That was the discovery of microwaves being a potential cheaper use of ovens.

Sorry, but that answer is totally i correct. People didn't know how to harness electricity in 1837... it was 1945, and the person whose chocolate bar melted was Percy Spencer of Raytheon (who only went to grammar school). He realized that microwaves heated the chocolate, then tried popcorn. Heat applied for a patent for heating food. After that, he and others at Raytheon worked at designing an oven that could be used for cooking. The result was something that looked like a 5 foot high refrigerator and weighed 600 - 700 pounds. It was in the 1960's that the first table top units were produced.
