Eli Whitney (December 8, 1765 – January 8, 1825) was an American inventor best known for inventing the cotton gin. This was one of the key inventions of the Industrial Revolution and shaped the economy of the antebellum South.[1] Whitney's invention made short staple cotton into a profitable crop, which strengthened the economic foundation of slavery. Despite the social and economic impact of his invention, Whitney lost his profits in legal battles over patent infringement, closed his business and nearly filed for bankruptcy.

Career inventions
Cotton gin
The cotton gin is a mechanical device which removes the seeds from cotton, a process which had been extremely labor intensive. The word 'gin' is short for engine. The cotton gin was a wooden drum stuck with hooks which pulled the cotton fibers through a mesh. The cotton seeds would not fit through the mesh and fell outside. Whitney occasionally told a story where he was pondering an improved method of seeding the cotton and he was inspired by observing a cat attempting to pull a chicken through a fence, and could only pull through some of the feathers.

A single cotton gin could generate up to 55 pounds of cleaned cotton daily. This contributed to the economic development of the Southern states of the United States, a prime cotton growing area; some historians believe that this invention allowed for the African slavery system in the Southern United States to become more sustainable at a critical point in its development.

Whitney received a patent (later numbered as X72) for his cotton gin on March 14, 1794; however, it was not validated until 1807. Whitney and his partner Miller did not intend to sell the gins. Rather, like the proprietors of grist and sawmills, they expected to charge farmers for cleaning their cotton - two-fifths of the value, paid in cotton. Resentment at this scheme, the mechanical simplicity of the device and the primitive state of patent law, made infringement inevitable. Whitney and Miller could not build enough gins to meet demand, so gins from other makers found ready sale. Ultimately, patent infringement lawsuits consumed the profits and their cotton gin company went out of business in 1797. One oft-overlooked point is that there were drawbacks to Whitney's first design. There is significant evidence that the design flaws were solved by a woman named Katherine Green; Whitney gave her no public credit or recognition.

While the cotton gin did not earn Whitney the fortune he had hoped for, it did give him fame.

And the cotton gin transformed Southern agriculture and the national economy. Southern cotton found ready markets in Europe and in the burgeoning textile mills of New England. Cotton exports from the U.S. boomed after the cotton gin's appearance - from less than 500,000 pounds in 1793 to 93 million pounds by 1810. Cotton was a staple that could be stored for long periods and shipped long distances, unlike most agricultural products. It became the U.S.'s chief export, representing over half the value of U.S. exports from 1820 to 1860.

Paradoxically, the cotton gin, a labor-saving device, helped preserve slavery in the U.S. Before the 1790s, slave labor was primarily employed in growing rice, tobacco, and indigo, none of which were especially profitable any more. Neither was cotton, due to the difficulty of seed removal. But with the gin, growing cotton with slave labor became highly profitable - the chief source of wealth in the American South, and the basis of frontier settlement from Georgia to Texas. "King Cotton" became a dominant economic force, and slavery was sustained as a key institution of Southern society.

Milling machine
Machine tool historian Joseph W. Roe credited Whitney with inventing the first milling machine. Subsequent work by other historians (Woodbury, Smith, Muir) suggests that Whitney was among a group of contemporaries all developing milling machines at about the same time (1814 to 1818). Therefore, no one person can properly be described as the inventor of the milling machine.

Later life and legacy
Despite his humble origins, Whitney was keenly aware of the value of social and political connections. In building his arms business, he took full advantage of the access that his status as a Yale alumnus gave him to other well-placed graduates, such as Secretary of War Oliver Wolcott (Class of 1778) and New Haven developer and political leader James Hillhouse.

His 1817 marriage to Henrietta Edwards, granddaughter of the famed evangelist Jonathan Edwards, daughter of Pierpont Edwards, head of the Democratic Party in Connecticut, and first cousin of Yale's president, Timothy Dwight, the state's leading Federalist, further tied him to Connecticut's ruling elite. In a business dependent on government contracts, such connections were
