๐ On This Day In History... ๐
๐ ๐ง๐ผ๐ฑ๐ฎ๐, ๐ข๐ฐ๐๐ผ๐ฏ๐ฒ๐ฟ ๐ด, marks the 79th anniversary of the patent Perry Spencer filed for the microwave oven. Spencer inadvertently invented the microwave oven while attempting to develop more powerful radar equipment in the 1940s.
๐ As a young man, Spencer had become interested in wireless communications after learning about wireless operators aboard the Titanic when it sank in 1912.
๐ Fast-forward a few years, Spencer became a self-taught expert on telegraph and radio, which led to a better job in the military - and later adding other scientific subjects, like trigonometry, calculus, chemistry, physics, and metallurgy.
๐ When his enlistment ended in 1925, Spencer did what many military veterans do: he got a job in the defense industry.
๐ By the late 1930s, he was one of the leading experts in radar tube design. As chief of the power tube division at Raytheon, he significantly improved the production of magnetrons, which ultimately led to a lucrative contract for the company during World War II.
๐ Toward the end of the war, Spencer was leading a project building magnetrons, when he noticed that a candy bar in his pocket melted.
๐ Intrigued that microwave technology might be harnessed for cooking, he started experimenting with other foods.
๐ Between 1964 and 1965, Raytheon built a legitimate kitchen-sized microwave and bought home appliance maker Amana.
๐ Within a decade after that, Americans bought more microwave ovens than regular gas or electric ovens.
๐ At the time of Spencer's death, he had more than 150 patents, passing away just a few years too soon to see just how successful his microwave invention had become.
๐ Today, we honor Perry Spencer for his discoveries and advancements in high-efficiency magnetrons and the invention of the microwave oven.
๐ Fun fact: Perry Spencer was a Maine native, born in the town of Howland.
