The History of the Microwave Oven
The microwave oven, a ubiquitous kitchen appliance, has an interesting history that spans several decades. The invention and development of this remarkable appliance have revolutionized the way we cook and heat our food.
The concept of using microwaves for cooking was discovered by accident. In 1945, an engineer and inventor named Percy Spencer was working on a radar-related project for Raytheon Corporation when he noticed something peculiar. He realized that the candy bar in his pocket had melted due to the microwaves emitted by an active radar set. This observation led Spencer to further explore the potential uses of microwaves.
Spencer and his team at Raytheon Corporation began experimenting with microwaves and food. They built a metal box called a “Radarange” and tested it by heating various food items, including popcorn kernels and an egg. To their surprise, the popcorn kernels popped and the egg exploded. These successes proved that microwaves could indeed be used for cooking.
In 1947, Raytheon Corporation introduced the first commercial microwave oven called the “Radarange”. This early microwave oven had a height of about 6 feet and weighed about 750 pounds. Despite its size and weight, the Radarange was an impressive appliance that cooked food quickly and efficiently. However, it was too expensive and large for household use.
Over the next few decades, various companies continued to develop and refine microwave ovens. In the 1960s, companies like Amana introduced countertop microwave ovens that were smaller and more affordable. These ovens gained popularity and became a common sight in kitchens around the world.
Today, microwave ovens come in different sizes and styles, ranging from compact models suitable for small apartments to larger models with advanced features. They have become an essential part of modern kitchens, providing a convenient and efficient way to cook and reheat food.

Development and Early Experiments
The development of the microwave oven began in the early 1940s, during World War II. The war effort required the invention of new technologies, and researchers were exploring ways to improve radar systems. During this time, Dr. Percy Spencer, an engineer at Raytheon Corporation, was working on magnetrons, which are vacuum tubes that generate microwaves.
One day, while Dr. Spencer was working with a magnetron, he noticed that a chocolate bar in his pocket had melted. Intrigued by this observation, he conducted further experiments by placing various food items near the magnetron. He discovered that microwaves could heat food quickly and efficiently.
In 1945, Raytheon Corporation filed a patent for the microwave cooking process. The first commercially available microwave oven, called the “Radarange,” was introduced in 1947. It was enormous, standing nearly six feet tall and weighing over 750 pounds. The cost of this early microwave oven was around $5,000, which made it prohibitive for most households.
In the 1950s, microwave ovens started to become more compact and affordable. Companies like Tappan introduced smaller countertop models that were more accessible to consumers. The popularity of microwaves grew throughout the following decades, as their convenience and time-saving capabilities became apparent.
Today, microwave ovens are a common household appliance. They have revolutionized the way we cook and reheat food, providing quick and efficient meal preparation. The concept and early experiments of Dr. Percy Spencer laid the foundation for this breakthrough technology, which continues to evolve and improve in modern times.
First Commercial Microwave Oven
The first commercial microwave oven was introduced in 1947 by the company Raytheon. It was called the “Radarange” and was marketed as a fast and efficient way to cook food.
