Percy LeBaron Spencer is considered to be the inventor of the microwave oven. He was working as an engineer with the Raytheon company when he was experimenting with and testing a magnetron. The magnetron had already been invented during WWII and allowed the Allies to determine the exact locations of Nazi war machines and arsenals, as the magnetron produced microwaves which radar then bounced off the arsenals, and back to the Allies.
The magnetron was passed to Raytheon in the USA for further development and 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.
On October 25, 1955, Tappan Stove Company sold the first domestic microwave oven, a large, 220V wall unit priced at $1295. Because of the price, it didn't sell well. In 1967, Amana, a division of Raytheon, introduced its domestic Radarange microwave oven, marking the beginning of the use of microwave ovens in home kitchens.
Raytheon filed a patent on October 8, 1945 for a microwave cooking oven, eventually named the Radarange. In 1947 the first commercially produced microwave oven was about 6 feet tall, weighed about 750 lbs, and cost between $2,000 and $3,000. In 1967 the first relatively affordable ($495) and reasonably sized (counter-top) microwave oven was available for sale.
PERCY WORKED FOR RAYTHEON.
In 1947, Raytheon demonstrated the world's first microwave oven and called it a "Radarange,"
the first microwave was 1997-now
i hope this help you ttyl
PEACE

What date did Percy L.Spencer invented the microwave oven and magnetron?
If I'm not mistaken, the first microwave unit was built in the Motorola labs while experimenting on a new radio technology. The person working on the device got too close to the magnetron (the microwave tube) and had a Hershey bar which he was holding in his back pocket and then the choclate bar melted melt. That also was a clue that microwave ovens were possible.
