Microwave oven
In 1947, Raytheon built the "Radarange", the first commercially available microwave oven. It was almost tall, weighed and cost about US$5,000 ($ in dollars) each. It consumed 3 kilowatts, about three times as much as today's microwave ovens, and was water-cooled. The name was the winning entry in an employee contest. An early Radarange was installed (and remains) in the galley of the nuclear-powered passenger/cargo ship NS "Savannah". An early commercial model introduced in 1954 consumed 1.6 kilowatts and sold for US$2,000 to US$3,000 ($ to $ in dollars). Raytheon licensed its technology to the Tappan Stove company of Mansfield, Ohio in 1952. They tried to market a large 220 volt wall unit as a home microwave oven in 1955 for a price of US$1,295 ($ in dollars), but it did not sell well.
Aaron L. Brody
Brody started his career, while in school, in food technology with the Birdseye Fisheries Lab Division of General Foods in 1951 as a team member in the development of the first frozen precooked foods including fish sticks. While a graduate student, he worked part-time for Raytheon Manufacturing Company where he was a member of a team that developed the first microwave oven, leading to microwave cooking, heating, and browning of foods. After he earned his graduate degree, Brody worked for the Whirlpool Corporation in Benton Harbor, Michigan. He led the development of modified atmosphere packaging (MAP), invented an odor control system for refrigerators, a thermoelectric refrigerator/freezer, the Total Environmental Control “Tectrol” controlled atmosphere process for food preservation, a progenitor of MAP fresh-cut vegetables, and radiation pasteurization of foods. While at Whirlpool, he invented and patented an apparatus and method of storing perishable animal and plant materials, as well as non-food materials.
