But the humble machine was actually created partially by accident – and partially because a nature-loving man wanted to feed the squirrels .

When was the microwave invented?
In 1945, American physicist Percy Spencer had been testing a radar magnetron – typically used today as the main frequency source in a microwave .
When it came to lunchtime, Spencer went to feed the squirrels with a peanut cluster he had been keeping in his pocket – only to find it had melted .
He experimented with placing an egg beneath the pipe, and it exploded in his face, so the adjacent day he made popcorn for all his colleagues .
He passed microwaves into a metallic element box, where they bounced around unable to get out. spencer realised this form of cooking was quicker than conventional heat ovens, and filed for his patent in 1945 .
Spencer was not the only person to notice the microwave cooking effect – but he was the first to be interest adequate to develop the theme .
In the early 1940s, british physicist Sir John Turton Randall and his team had developed the radar magnetron, which had been sold to american companies, including Raytheon, in change for serve during World War II .
The beginning ever commercial microwave, the Radarange, by Raytheon, went on sale a year late. It weighed closely 750 pounds, cost over $ 2,000 and apparently stood at five foot six high .
A domestic microwave appeared in 1955, but it was expensive besides, and microwaves were not low-cost adequate to be accepted into people ’ s homes until the Amana ’ s Compact Radarange hit the shelves in 1967.

By 1975, over one million microwaves a class were being sold in the US .
spencer happened upon his invention when working on how to mass-produce radar magnetrons and make them more mighty He managed to increase production from 17 to over 2,600 per day .
They are vacuum tubes, like electric whistles that create electromagnetic waves rather of reasoned .
They produce microwave radiation and are used in radar systems .
Who invented the microwave?
Percy Spencer invented the microwave after the en bunch he was planning to feed the squirrels turned into a gooey mess in his pocket while he was testing a military grade magnetron .
Spencer ’ s family were thus hapless he often had to hunt for his food in the wilderness where he grew up, in Howland, Maine .
He managed to become an engineer even though they had no electricity, no car, or modern appliances, and no conventional school. He worked at a bobbin mill when he was 12, installed electricity to another grind at age 14, then joined the united states navy because he wanted to learn about radios .
He continued to teach himself, reading borrowed books while he worked .
He started working for the american Appliance Company in the early 1920s, which became Raytheon Manufacturing Company in 1925 .
He made some significant artillery fuses for them which allowed shells to explode before hitting their prey.

today, Raytheon still makes missiles, military train systems and electronic war products .
spencer earned his locate in the National Inventors Hall of Fame, in Virginia, US, with over 150 patents to his name .
