When was the first microwave made? The shocking history

The microwave oven is one of the most commonly used kitchen appliances in the world. With its convenience and ease of use, it has become an essential part of all modern kitchens. As much as we rely on this device for quick meals and reheating leftovers, few of us know the compelling backstory of the invention of the first microwave oven.

In this article, we aim to break down the fascinating history of the first microwave oven, from its inception to today’s modern designs.

How did the microwave oven come into existence?

The history of the microwave oven dates back to the late 19th century when James Clerk Maxwell, a Scottish physicist, discovered electromagnetic radiation. In the 1930s, Percy Spencer, a self-taught engineer, was working on a radar system when he noticed that the candy bar in his pocket had melted. He connected the dots and realized that the electromagnetic radiation had caused that.

Spencer repeated the experiment and confirmed that microwave heating could also cook food. He then went to work on a prototype, which used microwaves to cook food quickly.

The first microwave oven

The first microwave oven was invented in 1945 by Percy Spencer. The microwave was much larger than those we know today, weighing over 700 pounds and standing over six feet tall.

The first microwave oven was not for home use; rather, it was an industrial model, designed for use in restaurants and other food service settings. The cost of the first microwave oven was around $5,000, equivalent to roughly $60,000 today.

The evolution of the microwave oven into a home appliance

The first microwave oven might not have been a success, but it inspired further research and development. Large companies invested in this technology, and it made the leap into the home kitchen a reality by the mid-1960s.

The first home microwave oven

The first home microwave oven was introduced by the Amana Corporation in 1967. It was a countertop model, priced at around $500, equivalent to roughly $4,000 today.

The oven was a hit with consumers, and it quickly gained popularity. Its affordability and versatility made it an essential appliance in homes across the US.
