Cotton gin. Interchangeable parts. Unintended consequences.

"One of my cotton gins will do more work in one day than the common mode of cleaning is capable of doing in thirty days."

Biography

Eli Whitney revolutionized American manufacturing through his cotton gin and the principle of interchangeable parts, fundamentally transforming both agriculture and industrial production. His innovations paradoxically intensified slavery's grip on the South while modernizing Northern factories, exemplifying how technological progress can amplify existing injustices.

Key Facts

  • Invented the cotton gin in 1793, which increased cotton processing speed by 50x but made slavery more profitable and entrenched
  • Pioneered the concept of interchangeable parts, laying the foundation for mass production and modern manufacturing
  • Spent years in patent litigation defending his cotton gin, receiving minimal financial return despite its massive impact
  • Designed muskets for the U.S. military using standardized, replaceable components—a revolutionary military manufacturing technique
  • Despite his brilliance, failed to anticipate or adequately address the moral consequences of his inventions

Invented progress. Accidentally built slavery's infrastructure. Consequences matter.
