In 1945, Raytheon engineer and inventor Percy Spencer stood in front of a magnetron—a radar component—and noticed a chocolate bar start to melt in his pocket. Curious about the magnetron’s potential, Spencer obtained a bag of popcorn kernels and watched them pop next to the magnetron. The microwave oven was born.
Radarange, the world’s first microwave oven, was 6 feet tall, weighed 750 pounds, and cost around $5,000.
