Percy Spencer: The Man Who Accidentally Invented the Microwave Oven

Readmikenow has written about respective aesculapian conditions. He has previously written a series of articles on Polyarteritis nodosa .Percy Spencer and first commercial microwave oven Percy Spencer and first commercial microwave oven Percy Spencer was a self-taught engineer who was hired by the Raytheon ship’s company in the 1920s. His hard influence and success led him to become one of the company ‘s most well known and most respect workers. Spencer had a repute as a give trouble problem solver. He helped develop many authoritative items for the military. One of them was detonators that enabled soldiers to trigger artillery shells, so they could explode before hitting their mark in mid-air. When he was testing a device called a magnetron, he noticed the microwaves from the device melted the cocoa bar he had in his pocket. Spencer was curious about why this happened. He continued testing other foods such as an egg, that exploded and covered his face. The adjacent day he brought corn whiskey kernels for testing. The magnetron microwaves popped all of them. Everyone in the office where he worked wanted to use their food on Spencer ‘s invention. The microwave was created.

Early Life

In 1894, Percy Spencer was born in Howland, Maine. At the senesce of 12, he dropped out of grammar school. Spencer then went to work in a weave mill as a spindle son. As a new man, he worked hard at teaching himself about electricity. Spencer became very skilled and was asked by a local paper factory to set up their modern electrical system. He was 18 when he joined the U.S. Navy in 1912. Spencer worked as a naval radio operator. During this time, he was busy using his barren meter to study many different scientific subjects. They included trigonometry, tartar, physics, chemistry deoxyadenosine monophosphate well as metallurgy, and more. While standing watch former at nox, Spencer would besides read textbooks that he had obtained .Raytheon Building Raytheon build up

American Appliance Company

spencer joined the american Appliance Company in Cambridge, MA soon after World War I ended. This caller soon became known as the Raytheon Company. The british signed a compress during World War II with Raytheon for the company to mass-produce one of their latest inventions : fight radar equipment. Britain was in a difficult situation in the war and in want of a means to detect german submarines american samoa well as planes. The primary component in their combat radar organization was the magnetron. Spencer created a way for the magnetron to be produced on a big scale. At its acme, over 2,500 were being manufactured in a day. A commodore from the U.S. Navy stated the radar equipment produced by Raytheon had a significant shock on all ocean engagements during World War II. Spender was awarded the Distinguished Public Service Award from the U.S. Navy. This is the highest civilian honor that can be given to a civilian by the Navy .

Microwave Discovery

It happened when Spencer was busy build magnetons. He was standing at the front of a radar set testing it. This is when he realized the bite in his pocket melted. Others had noticed such a phenomenon occur, but Spencer was the first gear person to begin investigating it. Spencer tried different foods including popcorn kernels. He then placed the high-density electromagnetic sphere inside of a metal box. This was the world ‘s first microwave oven. Spencer discovered the magnetron was able to emit microwaves into the alloy box. Doing this blocked the get off of the microwaves. This made it possible to have safe and controlled experiment. During the following days, he put different food items in the metallic box. He would observe the effects of the microwaves on the food and monitor their temperatures .Microwave drawing Microwave draw


On October 8, 1945, Raytheon filed a apparent for a microwave cooking oven. The name it was given was the Radarange. The first commercial microwave oven was built in 1947. It weighed approximately 750 pounds and was 6 feet grandiloquent. The cost of a Radarange at this time was $ 5,000. The first low-cost microwave oven was released in 1967. It cost $ 495. Its size was small enough to be put on a counter-top .1967 Microwave oven 1967 Microwave oven


Spencer was finally made a senior Member of Raytheon ‘s Board of Directors. He was besides made a senior Vice President. During his career, Spencer obtained over 300 patents. There is a building in Woburn, Massachusetts at Raytheon ‘s Missile Defense Center that is named in his honor. The University of Massachusetts gave Spencer an honorary doctor of the church of Science, he was besides given a Fellowship in the Academy of Arts and Sciences. His achievements were impressive considering he had no formal education .

No Royalties

For his work associated with inventing the microwave oven, Spencer was not given any royalties. Raytheon gave him a erstwhile gratuity of $ 2.00. This is what the company paid all those employees at the time who created things the company could obtain a patent for inventing .


Percy Spencer died on September 8, 1970. He was 76 years old. He was buried after a service at St. John ‘s Episcopal Church.

Most homes around the world adenine well as businesses have one. It is a popular appliance for reheating previously cooked foods. A microwave is besides much used to cook a variety of foods. The world of food training was changed forever by Percy Spencer ’ s invention of the microwave oven .

Pamela, thanks. I agree. Pamela Oglesby from Sunny Florida on September 23, 2020 : Percy Spencer was obviously a brilliant man, flush without a ball education. This is a very concern article, Mike .
