Born in Peru, NY , Pratt designed a Milling Machine for the George S. Lincoln company of Hartford, Connecticut which became the Lincoln Miller , the most important American Machine Tool of the late 1800s , with 150,000 sold. With Amos Whitney he organized Pratt & Whitney in 1860 to manufacture machine tools, tools for the makers of sewing machines, and gun making machinery for use by the Union Army during the American Civil War . He is credited with being first to permit production of fine gear work. Pratt promoted interchangeable parts and the adoption of a standard system for gages for the United States and Europe .
