Spencer was born in Howland, Maine, orphaned at a young age, and raised by his aunt and uncle.
In 1941, magnetrons, which were used to generate the microwave radio signals that are the core mechanism of radar, were being made at the rate of 17 per day at Raytheon.

Percy Spencer, född 9 juli 1894, död 8 september 1970, är uppfinnaren bakom mikrovågsugnen, när han en dag gick fram till en magnetron så märkte han att godis i hans ficka smälte.
Spencer blev genast intresserad och började experimentera, han lade t.ex några majskorn vid magnetronen, och resultatet blev popcorn.
Spencer sökte patent på sin uppfinning, och den första kommersiella mikrovågsugnen producerades av Raytheon år 1947.

The story is typical of Percy Spencer's direct, homey approach, which he brings even to the miracle world of modern electronics.
When Spencer found out the man was bald, he said, "Come with me." At the office of Raytheon president Charles Francis Adams, he flung open the door on the startled Adams, who is as bald as his great-great-grandfather, the second President of the United States, and his great-grandfather, the sixth U. President.
For Percy Spencer, the orphan who never went beyond grammar school, has amply demonstrated that nothing is beyond the grasp of a man who wants to know what is going on, and who feels a sense of responsibility for doing something about it.

Now that Rod Spencer is in fact a rocket scientist, he still waves both hands when greeting family, to show he hasn't exceeded the limitations of his ingenuity.
Spencer says his system costs less, is simpler, and promises more flexibility than other products, since it is designed to readjust itself to changes in machinery.
Because Spencer's system can be used to build a database that catalogs how different equipment in a factory has reacted in the past to different situations, the system can effectively teach itself to solve problems on its own.

Percy Spencer joined the navy and learned about radios in his capacity as a wireless man. Following the service he got a job at Raytheon, a manufacturer of vacuum tubes.
At this point Percy Spencer should have invoked Thomas Edison's famous admonition: "There ain't no rules around here, we're trying to accomplish something." Spencer and Raytheon (they had the good sense to know which horse to bet on) ignored them and of course it worked.
One day, years later, Percy Spencer walked up to an energized magnetron and noticed that a chocolate bar had gone all hot and gooey in his shirt pocket.

Whatever it was, Spencer recognized the possibility of heating foods with microwave energy -- the same energy used in radar -- and invented the microwave oven.
His patent, filed in October 1945 and granted in 1950, (U.S. patent 2,495,429) can be paraphrased as: a method of treating food by application of microwave energy, wherein the food is exposed to microwave energy within a restricted region of space and for sufficient time to cook the food to a predetermined degree.
Percy Spencer's chance encounter with microwaves certainly was a significant step in modern cooking.
