History of National Microwave Oven Day

The microwave oven’s story starts in the second phase of the World War in the 1940s. Percy Spencer, an engineer at Raytheon Corporation, accidentally discovered that microwave radiation can be used for cooking. A melted candy bar in his pocket led to this realization while he was doing experiments with a magnetron, a type of vacuum tube that generates microwaves.

Spurred on by his observation, Spencer decided to delve deeper into the heat-producing properties of microwaves. He put popcorn near the magnetron and observed it pop. He also put an egg that ended up heating rapidly and bursting. These experiments eventually paved the way for the invention of the first microwave oven, which was referred to as the “Radarange.”

In 1945, Raytheon formally filed a patent for Spencer’s revolutionary way of cooking using microwaves. By 1947, the first microwave ovens were commercially manufactured and sold by Raytheon. However, these early microwaves were bulky and costly, thus making them inaccessible for ordinary households.

The first compact and reasonably priced microwave oven intended for household use was finally introduced to the public market by Raytheon in 1967. Thanks to technological advancements, Amana Radarange, saw an increased demand and had become a household staple from the late 1970s and throughout the early 1980s. Microwave ovens are now indispensable in kitchens worldwide.

7 Interesting Facts About Microwave Oven


Invented by accident

The microwave oven was invented completely by accident in the 1940s by an engineer named Percy Spencer. While working on radar technology, Spencer noticed a chocolate bar in his pocket had melted from the microwaves, paving the way for the microwave oven.


First microwave was enormous!

The very first microwave oven weighed about 750 pounds and stood about 5 feet 6 inches tall. Imagine having to fit that in your kitchen!


Microwaves don’t cook food from the inside out

Contrary to popular belief, microwaves don't cook food from the inside out. They actually heat up the outer layers, while the inside gets cooked by the heat transferring inwards.


Originally named 'Radarange'

When the first 'Radarange' hit the market in 1947, it costed up to $5000 - a price tag that is comparable to around $60,000 today when adjusted for inflation!


Popcorn and Microwave

Popcorn was one of the first foods that were tested in a microwave and microwave popcorn is one of the single largest uses of microwave ovens today.


Use less energy than conventional ovens

Microwaves are more energy efficient than traditional ovens because they concentrate heat directly on the food. Traditional ovens can use up to 3 times more energy.


Microwave Cooking does not kill nutrients

Any form of cooking will destroy some nutrients in food, but the key variables are how much water is used in the cooking and how long the food is cooked - making microwave better for preserving nutrients than most cooking methods.
