When it comes to modern kitchen appliances, the microwave oven is considered one of the most revolutionary inventions of the 20th century. In today’s fast-paced world, it’s hard to imagine a kitchen without a microwave. However, it wasn’t until the mid-20th century that the first microwave oven was introduced to the world, forever changing the way we cook and reheat our food.
The first microwave oven, known as the “Radarange,” was developed in the 1940s and 1950s through a collaboration between Percy Spencer, an American engineer and inventor, and Raytheon, a defense contractor. Spencer, who worked on radar technology during World War II, discovered the heating effect of microwaves when a chocolate bar in his pocket melted while he was conducting experiments.
It was in 1945 that Spencer and his team at Raytheon filed a patent for the first microwave cooking oven. The initial models were massive and bulky, weighing around 750 pounds (340 kg) and standing at over 5 feet (1.5 meters) tall. They were primarily used in industrial settings, such as restaurants and large-scale food production facilities.
However, it wasn’t until 1967 that the first countertop microwave oven became available for home use. The Amana Corporation, a subsidiary of Raytheon, introduced the first compact and affordable microwave oven for residential kitchens. With a cost of around $495, equivalent to over $3,700 in today’s money, it was still a luxury appliance accessible to only a few households. Nevertheless, its popularity grew rapidly, and by the late 1970s, the microwave oven became a common feature in kitchens worldwide.
History of Microwave Ovens
The history of microwave ovens dates back to the early 1940s, during World War II. The development of microwave technology can be credited to Percy Spencer, an American engineer. While working at the Raytheon Corporation, he noticed that a candy bar in his pocket had melted after standing near a magnetron, a vacuum tube used for radar systems.
Spencer’s curiosity led him to conduct further experiments, which eventually resulted in him inventing the first microwave oven. In 1945, Raytheon introduced the “Radarange,” the first commercial microwave oven, which was primarily used in restaurants and large-scale food processing industries.
As the technology advanced, microwave ovens became smaller, more affordable, and suitable for home use. In 1967, Amana, a subsidiary of Raytheon, introduced the first countertop microwave oven for residential kitchens. This innovation revolutionized the way people cooked and heated their food.
Over the years, microwave ovens have become indispensable appliances in households worldwide. They offer convenience, speed, and efficient cooking, making them a staple in modern kitchens. Today, microwaves come in various sizes, features, and designs to cater to different cooking needs and preferences.

The Invention of the Microwave Oven
The microwave oven, a common household appliance today, was an innovative invention that revolutionized cooking. It was a result of years of scientific research and development.
Early Development
The foundation for the microwave oven was laid in the early 1940s when scientists started experimenting with magnetrons, which are vacuum tubes that generate microwaves. These microwaves are a type of electromagnetic radiation with wavelengths ranging from 1 millimeter to 1 meter. Researchers discovered that these microwaves could heat food quickly and efficiently.
One of the first individuals to see the potential of using microwave technology for cooking was Percy Spencer, an American engineer. While working on radar technology during World War II, he noticed that a chocolate bar in his pocket had melted after being exposed to microwaves. Realizing the potential of this discovery, Spencer went on to further experiment with using microwaves to cook food.
The First Microwave Oven
In 1947, the first commercially available microwave oven was introduced. It was called the “Radarange” and was created by the Raytheon Corporation. This early microwave oven was much larger and more expensive than the ones we see today. It stood around 6 feet tall and weighed around 750 pounds. At a price of about $5,000, it was primarily used in commercial settings such as restaurants and hotels.
Over the years, advancements in technology made microwave ovens more accessible and affordable. By the 1970s, countertop microwave ovens became popular among households, allowing for convenient and quick cooking. Today, microwave ovens are a staple in most kitchens, offering a simple and efficient way to heat or cook food.
The First Commercial Model
The first commercial microwave oven was introduced in 1947 by Raytheon under the name “Radarange”. It was a huge countertop appliance that was primarily marketed to restaurants and industrial kitchens. It was approximately 6 feet tall and weighed around 750 pounds, making it impractical for home use.
The Radarange was incredibly expensive, with a price tag of around $5,000 (equivalent to around $55,000 today). Despite its high cost, it quickly gained popularity in the food industry due to its ability to heat and cook food much faster than traditional methods.
The early models of the Radarange had some drawbacks. They were difficult to operate and required specially trained technicians to install and maintain. Additionally, they posed some safety risks, as the technology was still relatively new and not fully understood.
Improved Consumer Models
In the 1960s, smaller and more affordable microwaves started to appear on the market. Companies such as Amana and Litton Industries began producing microwave ovens for consumer use. These models were smaller, safer, and easier to use than the earlier commercial versions.
The improved consumer models offered various cooking features and presets, making them more versatile and user-friendly. They quickly gained popularity among households, revolutionizing cooking by allowing people to heat up leftovers and cook meals in a fraction of the time.
Over the years, microwave ovens have continued to evolve, becoming a staple appliance in kitchens worldwide. They have become more compact, energy-efficient, and technologically advanced, offering features such as convection and steam cooking.
