Whitney, Eli, 1765-1825, American inventor of the cotton gin, b. Westboro, Mass., grad. Yale, 1792. When he was staying as tutor at Mulberry Grove, the plantation of Mrs. Nathanael Greene, Whitney was encouraged by Mrs. Greene and visiting cotton planters to try to find some device by which the fiber of short-staple cotton could be rapidly separated from the seed. Whitney, whose creative mechanical bent had been evident from boyhood, completed his model gin early in 1793, after about 10 days of work, and by April had built an improved one. With Phineas Miller, Mrs. Greene's plantation manager (and later her husband), he formed a partnership to manufacture gins at New Haven. He was unable to make enough gins to meet the demand, and although the partners received a patent in 1794, others copied his model and soon many gins were in use. After much litigation the partners received (1807) a favorable decision to protect their patent, but Congress in 1812 denied Whitney's petition for its renewal. His invention, which had immense economic and social effects, brought great wealth to many others, but little to Whitney himself. In 1798 he built a firearms factory near New Haven. The muskets his workmen made by methods comparable to those of modern mass industrial production were the first to have standardized, interchangeable parts.

The Eli Whitney Museum, in Hamden, Connecticut, focuses on design and invention with hands-on projects and exhibits on Eli Whitney and A. C. Gilbert.

The museum building was originally the Eli Whitney Armory, erected by Whitney to produce muskets on a site he purchased on September 17, 1798. The factory was powered by water from the Mill River and produced muskets for the United States government. On June 14, 1798, he contracted to produce 10,000 muskets to be delivered within 28 months at the cost of $134,000.00; in fact, it took ten years. When he signed the contract, Whitney had no factory, no workers and no experience in gun manufacturing. However, in a letter to Secretary of the Treasury Oliver Wolcott, a fellow Yale University graduate and friend, Whitney had written:

I am persuaded that Machinery moved by water adapted to this Business would greatly diminish the labor and facilitate the manufacture of this Article. Machines for forging, rolling, floating, boring, grinding, polishing, etc. may all be made use of to advantage.... (May 13, 1798)

Whitney's factory was at the very forefront of the American Industrial Revolution, using water-powered machinery, and it was among the first to have standardized, interchangeable parts (for some but not all of its parts).

The Eli Whitney museum has exhibits on Whitney and his most famous invention, the cotton gin. Other exhibits cover the historic site and A. C. Gilbert, the inventor and toy maker best known for his invention of the erector set. The museum is an experimental learning workshop for design and specializes in building projects for children blending science and invention. The site is located near a water reservoir as well as a hiking trail and also includes a reconstruction of Ithiel Town's innovative lattice truss covered bridge. The museum hosts summer programs and birthday parties.
