On November 11, 1911, Louis Upton (Lou), who worked as an insurance salesman, and his uncle, Emory Upton, who owned a machine shop, founded the Upton Machine Company. Following a failed business venture, Lou acquired a patent to a manual clothes washer. With the aid of a $5,000 investment from retailing executive Lowell Bassford, they began producing electric motor-driven wringer washers. Soon after its founding, Lou's younger brother Fred joined the company.
In 1916, Sears, Roebuck and Co began selling two types of Upton wringer washers under the "Allen" brand, one for $54.75 and a deluxe model for $95. Sales grew quickly and in 1921, Sears appointed Upton as their sole supplier of washers. To avoid becoming over-reliant on Sears, Upton began marketing a washer under their own brand name.
The increasing volume of sales led Upton to merge with the Nineteen Hundred Washer Company of Binghamton, New York in 1929, adopting the name Nineteen Hundred Corporation. During WWII, its factories were converted to armament production. In 1947 it introduced an automatic, spinner-type washer sold by Sears under the "Kenmore" brand. A year later it was sold by the company under the "Whirlpool" brand name.
In response to the post-war consumer demand for convenience products, the company launched a range of home laundry products including wringer and automatic washers, dryers, and irons. In 1950, The Nineteen Hundred Corporation was renamed as the Whirlpool Corporation.
In 1988, Whirlpool bought a 53% stake in the large-appliance division of Philips N.V., creating a joint venture called Whirlpool International. The purchase made Whirlpool the world's largest manufacturer of major appliances, with annual sales of approximately $6 billion.
Since then, Whirlpool Corporation has become the world's leading producer of major household appliances. Its main products include home laundry equipment, dishwashers, refrigerators, freezers, ovens, ranges, room air conditioners, and mixers and other small household appliances.
The company's appliances are sold in more than 170 countries worldwide under such brand names as Whirlpool, KitchenAid, Roper, Estate, Bauknecht, Ignis, Laden, Polar, Brastemp, Consul, and Eslabon de Lujo.
