Eli Whitney Jr. (December 8, 1765 - January 8, 1825) was an American inventor, widely known for inventing the cotton gin, one of the key inventions of the Industrial Revolution that shaped the economy of the Antebellum South.
Although Whitney himself believed that his invention would reduce the demand for enslaved labor and help hasten the end of southern slavery, Whitney's invention made upland short cotton into a profitable crop, which strengthened the economic foundation of slavery in the United States and prolonged the institution. Despite the social and economic impact of his invention, Whitney lost much of his profits in legal battles over patent infringement for the cotton gin. Thereafter, he turned his attention to securing contracts with the government in the manufacture of muskets for the newly formed United States Army. He continued making arms and inventing until his death in 1825.
Whitney was born in Westborough, Massachusetts, on December 8, 1765, the eldest child of Eli Whitney Sr., a prosperous farmer, and his wife Elizabeth Fay, also of Westborough.
The younger Eli was famous during his lifetime and after his death by the name "Eli Whitney", though he was technically Eli Whitney Jr. His son, born in 1820, also named Eli, was known during his lifetime and afterward by the name "Eli Whitney Jr."
Whitney's mother, Elizabeth Fay, died in 1777, when he was 11. At age 14 he operated a profitable nail manufacturing operation in his father's workshop during the Revolutionary War.
Because his stepmother opposed his wish to attend college, Whitney worked as a farm laborer and school teacher to save money. He prepared for Yale at Leicester Academy (now Becker College) and under the tutelage of Rev. Elizur Goodrich of Durham, Connecticut, he entered in the fall of 1789 and graduated Phi Beta Kappa in 1792. Whitney expected to study law but, finding himself short of funds, accepted an offer to go to South Carolina as a private tutor.
Instead of reaching his destination, he was convinced to visit Georgia.
