Eli Whitney
The Library of American Lives and Times
The inspired mechanical genius of Eli Whitney was responsible for innovations that gave the United States its great advances in industrialization. His invention of the cotton gin, a machine that separated cotton fiber from the plant's seeds, revitalized the Southern economy. His later invention of interchangeable parts, which he first used to secure a government contract to produce a large number of guns, laid the foundation for the American system of manufacturing.
