Raytheon later licensed its patents for a home-use microwave oven that was introduced by Tappan in 1955, but it was still too large and expensive for general home use. Sharp Corporation introduced the first microwave oven with a turntable between 1964 and 1966.
Yes, the microwave oven was invented accidentally, when a test for a magnetron melted an engineer’s snack in 1946.. Raytheon engineer Perry Spencer “knack for finding simple solutions to ...
Raytheon patented the dielectric heating device, naming it the Radarange, and in 1947 the first commercially available microwave oven hit the market. What started as an 800-pound device priced ...
After earning his Ph.D. in 1955, Decareau worked for Raytheon in Allston on microwave technology that would lead to the development of the microwave oven. [2] Decareau's wife, Rosa, commented that a lot of work on the microwave oven was done at their home. [2] Then at Lipton, he was involved in freeze drying. [1]
He investigated cooking with microwaves and invented the microwave oven, consisting of a magnetron feeding microwaves into a closed metal cavity containing food, which was patented by Raytheon on 8 October 1945. Due to their expense microwave ovens were initially used in institutional kitchens, but by 1986 roughly 25% of households in the U.S ...
In 1967 the first more affordable, $495 (equivalent to $4,523 in 2023), and reasonably sized (counter-top) Radarange brand microwave oven was made available for sale, produced by Amana (a division of Raytheon). [4] Spencer became Senior Vice President and a Senior Member of the Board of Directors at Raytheon. He received 300 patents during his ...
Amana was acquired in 1965 by Raytheon, [7] which had invented the microwave oven in 1947, and introduced the commercial Radarange Model 1611 in 1954. [5] In 1967, Amana introduced a consumer model of the Radarange , the first popular microwave designed for home use.
William C. Brown (May 22, 1916 – February 3, 1999) was an American electrical engineer who helped to invent the crossed-field amplifier in the 1950s and also pioneered microwave power transmission in the 1960s. Brown received his BSEE from Iowa State University in 1937, and his MSEE from the Massachusetts Institute of Technology in 1941.
