Biographical / Historical:
John Gunnarson, a former employee of Raytheon, formed the Servodyne Company (1960), which made prototypes of the microwave oven. The company sought to bring microwave technology into the home for everyday use in a time when microwaves and their safety were under scrutiny. Developed by Gunnarson, Roger F. French, and Donald R. Lester, this prototype utilized klystrons instead of the magnetrons used by competitors. The company applied for a patent in 1966, but the oven was never successful. Servodyne Company struggled with financial issues and leadership changes, and the business folded in 1968 due to lack of funding. The liquidation process lasted until 1971.
