Eli Whitney Receives Patent for Cotton Gin
By the late 18th century, short-staple cotton was difficult to process profitably in the American South due to the labor-intensive task of separating seeds from fiber. While visiting Georgia, Yale graduate Eli Whitney observed the challenges and developed a mechanical device using a rotating cylinder with teeth to pull fibers through a grid, leaving seeds behind. He filed for a patent in late 1793, and on March 14, 1794, the U.S. Patent Office granted him Patent No. X72. The invention allowed a single operator to clean up to 50 pounds of cotton daily, far exceeding hand labor. Whitney's machine quickly spread despite patent disputes and copies by others.
