The Amana Corporation was founded by George Foerstner as Amana Refrigeration in 1934 in Middle Amana, Iowa, to manufacture commercial walk-in coolers. In 1947, the company created the first upright Amana freezer for the home, and in 1949 added a side-by-side Amana refrigerator-freezer. In 1950, the company was sold back to its founder and a group of other investors, and became Amana Refrigeration, Inc., starting their air conditioner line in 1954. Amana was acquired in 1965 by Raytheon, which had invented the microwave oven in 1947, and they introduced the original commercial Radarange in 1954.
In 1967 Amana introduced a consumer model of the Radarange, the first popular Amana microwave designed for home use. Amana has since expanded into a variety of other appliances including furnaces, Amana ovens, Amana countertop ranges, Amana dishwashers, and a wide range of Amana washers and Amana dryers. In 1997 the company was purchased by Goodman Global, a heating-and-cooling company which carried on the Amana Tradition. Amana transferred to the Maytag Corporation in 2001, but as of 2006, Amana home appliances are now owned and manufactured by the Whirlpool Corporation. Goodman still owns the Amana air conditioners and heater division. Through advancing technology, the ever-increasing needs of customers, and multiple shifts in ownership, Amana's incredible ability to adapt to change reflects well of the consistent high quality of its products.
