The microwave was found in the 20's. These were found by a set of army men on their radio when one set his food on the radio and it got warm. He started asking questions why. It took a few years to find out why.
Actually, it was during WWII. There were no devices capable of working at microwave frequencies until the war. For a short history, Wiki's got the right story (I've heard it in other sources)
"Cooking food with microwaves was discovered by Percy Spencer while building magnetrons for radar sets at Raytheon. He was working on an active radar set when he noticed that a peanut chocolate bar he had in his pocket started to melt. The radar had melted his candy bar with microwaves. The first food to be deliberately cooked with Spencer's microwave was popcorn, and the second was an egg, which exploded in the face of one of the experimenters.[1] To verify his theory, Spencer created a high density electromagnetic field by feeding microwave power into a metal box which it had no way to escape. When food was placed in the box with the microwave energy, the temperature of the food rose rapidly."
