Hall-Scott was founded in 1910 by E. Hall and B. Scott in Berkeley, California. The company was among the most significant builders of water-cooled aircraft engines prior to World War I in the USA.

History

Hall-Scott was founded in 1910 by Elbert J. Hall and Bert C. Scott, initially to produce powered passenger rail cars. Hall-Scott aero engine production also began in 1910.

Shortly after WW I, Hall-Scott dropped its aero engine and rail car product lines. The firm produced several hundred thousand two-speed rear axles for the Model T, the "Ruckstell Axle", through the mid-1920s. American Car and Foundry purchased Hall-Scott in 1925 and used its engines in its buses and boats.

In 1931, one of the firm's most famous and important products, the Invader, a marine engine, entered production. The company attained its highest production and employment numbers in World War II, building engines for a variety of military boats and a tank retriever. Hall-Scott engines were used in some Higgins Boats, the LCVP. Some post WWII ACF-Brill busses used by Greyhound and Trailways, used Hall-Scott engines.

ACF divested itself of Hall-Scott in 1954, and the division was purchased by Hercules Motors in 1958.

The final products bearing the Hall-Scott name were produced by Hercules in the late 1960s.
