  3. 3. Early Life Eli Whitney was born December 8th 1765 in Westborough Massachusetts. His mother diedwhen he was only 11 years of age so he was under the care of his father for the better part of his childhood. Whitneys mechanical genius began to be displayed at the age of 14 when he ran a nail production operation out of his father’s barn during the American Revolution. Among working on his nail operation he worked as a blacksmith and was one of the leading maker’s of ladies’ hatpins in his county. “He had an instinctive understanding of mechanisms. It was a medium in which he could improvise and create in exactly the same way that a poet handles words or a painter uses color.”
  4. 4. Early life (continued)Whitneys wished to attend college but was unable to due to the objection of his parents. Awish to attend a school such as Yale, when not studying law or theology, was absurd. Heinstead worked as a school teacher and a farmer. Whitney studied at Leicester Academywhile working and saving money. Eventually he saved enough money and entered the classof 1789 at Yale. After receiving his degree, Whitney took a job as a teacher in South Carolina because he could not find a job that appropriated his talents. He ended up living with Mrs. Greene, a Revolutionary war widow of general Nathanael Greene, after turning down his teaching job. The pay that Whitney committed to was not going to be met, so he lived with Mrs. Greene while reading law. Quit Nathanael Greene
  5. 5. Invention of the Cotton Gin Whilst listening to conversations among Mrs. Greene and neighbors, Whitney learned of the lack of a cash crops in the south. The amount of labor required to harvest green seed variety cotton was preposterous. It was at this point that Mrs. Greene spoke up and nominated Whitney to find a solution to one of the biggest problems of the South."Gentlemen," said Mrs. Greene, "apply to my young friend, Mr. Whitney. He can make anything."
  6. 6. Invention of the Cotton Gin (continued)Whitney began to watch closely at the harvesting and cleaning of cotton seeds. He noticedthat typically one hand held the seed and the other hand teased out the strands of lint.Whitney took the initiative to design a machine that merely duplicated the motion of thehands. Whitney made essentially a sift of wires that stretched lengthwise across themachine. This was to replace the hand that held the seed.There was a drum that rotated very closely to the wires. This drum had very fine wires onthe end so the lint would catch as it passed through. This was to replace the figures. Then arotating brush would spin and wipe the drum clean of lint. This brush spun four times asfast as the drum to make sure to gather all the lint. Click here to view a movie on the Cotton Gin Quit
  7. 7. BenefitsWhitney’s invention had sparked the morale of the South. They now had a cash cropthat would have dramatic effects on their economy. The United States no longer had tohave an enormous dependency on foreign cotton.Whitney’s Cotton Gin design has been onethat has changed little in the past twohundred years, showing his mechanicalgenius and understanding. Present dayCotton Gin’s have become larger to accountfor an increase in demand of cotton since theearly 19th century. A Cotton Gin near Moscow, Kansas Quit
  8. 8. ConsequencesWhitney and his partner, Phineaus Miller, did not have a great start with their newinvention. Although President Thomas Jefferson awarded the duo their patent in 1794,and wished to purchase one, this simply would not be so easy. Whitney and Miller hadpromised too many farmers too many gins and the price was outrageous.Farmers soon realized, that due to the simplicity of Whitney’s design, they could createhomemade gins and save money and time. The patent that Whitney had sought afterhad become essentially useless.Whitney’s revolutionary idea would also become one of the leading contributors andfactors of the beginning of the American Civil War. Slavery in the United States was ona decline due to the intense amount of labor required. The Cotton Gin solved thisissue, allowing more cotton to picked by more hands. Quit
  9. 9. Later Life In 1798 Whitney signed a contract with President Adams agreeing to produce 10,000 muskets in just two years time. This was a courageous agreement for a couple of reasons: Whitney did not own a factory nor have gunsmiths and he had never even produced a musket before. Whitney’s plan was to replicate ideas circulating in Europe at the time. Ideas of interchangeable parts, which would speed production greatly. Whitney created a self- sustaining community where he provided housing, food, and training for his employees. Whitney was unable to meet the goals of his agreement. It took him nearly 8 years to fill the order that he thought could be done in two.Until Whitney’s idea of interchangeable parts, all rifleparts made were made individually
  10. 10. Later Life (continued)Whitney became engulfed in his work and became very lonely. His partner, Miller,married Mrs. Greene. Whitney had his nephews, Philos and Eli Whitney Blake, come toNew Haven, CT and had them trained and educated. At the age of 51, Whitney marriedHenrietta Edwards, who was 31 at the time. Whitney began to fall ill. He was havingissues with an enlarged prostate. He started studying anatomy with his physicians andhelped devise a catheter to ease the pain.In 1825, Whitney died on January 8th.When his last notes were examined,they showed not signs of suffering butof thought on his work.
