Born December 8, 1765 - Died January 8, 1825
Inducted to the U.S. National Inventor's Hall of Fame in 1974 for the Cotton Gin, Patented March 14, 1794
American inventor, pioneer, echanical engineer, and manufacturer Eli Whitney is best remembered as the inventor of the cotton gin. He also affected the industrial development of the United States when, in manufacturing muskets for the government, he translated the concept of interchangeable parts into a manufacturing system, giving birth to the American mass-production concept. Born in Westboro, Massachusetts, Whitney decided in 1783 to get a college education. His own efforts were supplemented by his father's financial help, and after six years preparation he was admitted to Yale College, graduating in 1792. Whitney saw that a machine to clean the seed from cotton could make the South prosperous and make its inventor rich. He set to work at once and within days had drawn a sketch to explain his idea; 10 days later he constructed a crude model that separated fiber from seed. After perfecting his machine he filed an application for a patent on June 20, 1793; in February 1794 he deposited a model at the Patent Office, and on March 14 he received his patent. Whitney's gin brought the South prosperity, but the unwillingness of the planters to pay for its use and the ease with which the gin could be pirated put Whitney's company out of business by 1797. When Congress refused to renew the patent, which expired in 1807, Whitney concluded that 'an invention can be so valuable as to be worthless to the inventor.' He never patented his later inventions, one of which was a milling machine. His genius as expressed in tools, machines, and technological ideas made the southern United States dominant in cotton production and the northern states a bastion of industry.
During his illustrious career Whitney also worked as a blacksmith, developed and operated a machine which made nails, and for a time was the country's sole maker of ladies' hatpins. After receiving a degree at Yale at the age of twenty-seven, Whitney accepted a position as a tutor in South Carolina that promised a salary of one hundred guineas a year. On the journey, he became acquainted with the widow of Nathanael Greene, a Revolutionary general. When Whitney arrived, he was informed that the promised salary was going to be halved.
Mrs. Greene intended to marry one Phineas Miller, and Whitney ended up living on his farm and working for him, doing odd jobs. During the term of his employment there, he was persuaded to inspect the job of creating a machine which would remove the seeds from Green Seed Cotton, the only type which would grow in the region. For his troubles, he was repaid by the planters pirating his invention. He ended up being paid about $90,000 by various states, most of which was owed for legal costs and other expenses. The states then repudiated their agreements, and sued him for the money they had paid out to him. In 1804 Whitney applied to the federal Congress for relief, which was granted by one vote.
While best-known for the cotton gin, Whitney was involved in many other enterprises which changed the way the world operates today. He invented a system of machining in which an unskilled worker could produce parts for complicated devices, using templates.
