Allis-Chalmers were formerly E. P. Allis of Milwaukee in the 1840s and made waterwheel, sawmill and grindstones.

Incorporated in Delaware, the company soon became a major manufacturer of steam engines and industrial equipment in the Milwaukee area after merging in 1901 with other firms — Fraser and Chalmers were a large steel and mining retort manufacturer, and Gates Iron Works of Chicago[1]

1914 Allis-Chalmers entered into the farm equipment business at about the time of the World War I. The company would also play a major part as a manufacturer in the World War II building pumps for uranium separation as part of the Manhattan Project and building electric motors for U.S. Navy submarines. Allis-Chalmers also built triple expansion marine steam engines for Liberty ships.

The company introduced a number of product lines including Agricultural Tractor, Implements, Industrial Tractor, Gleaner Combines, Hydroturbines, Valves and Pumps, Compressors, Electric Motors, Crushing and screening equipment, Comminution, Air Purification, Coal Gasification and Simplicity Garden Tractors
