Donald Lamont Brown

Born in Berlin, Wisconsin, Donald L. Brown was an early innovator of aviation.

Aviation Career Begins

As a young man, Brown worked as a newspaper carrier, journalist, store clerk, and steel worker. After attending Northwestern University, he started his aviation career at Simplex Automobile Company.  He served as head of engine assembly. He later became a factory manager for Wright Aeronautical Corporation.

Pratt & Whitney Aircraft

Brown held several positions within the aviation industry before co-founding Pratt & Whitney Aircraft Company. In 1925, Pratt & Whitney Tools loaned $250,000, use of its name, and space in its building for the new venture.

With Frederick Rentschler and others, Brown sought to produce lighter-weight engines with greater power. Its first engine, the 425 horsepower R-1340 Wasp, powered the aircraft of many record flights.

United Aircraft Corporation

In 1930, Brown became president of United Aircraft Corporation (the later name of Pratt & Whitney Aircraft). As president, he led the company to become one of the world’s largest producers of airplanes, engines, and propellers.
