1. “…he can make anything…”

2. Basic Biographical Data 1765 - Born in Westborough, MA 1792 - Graduated from Yale University 1793 – invented the cotton gin 1798 – built a musket factory using the concept of interchangeable parts and a simple assembly line process 1825 – died in Connecticut

3. Why is Whitney Important? On trip to SC plantation, EW noticed slaves working hard 1793 – invented the cotton gin to help slaves clean cotton faster and easier to improve productivity to increase profits for plantation

4. The Cotton Gin Raw cotton goes in Roller combs rip cotton fibers apart Seeds fall to the bottom Clean cotton collects here Hand crank to turn the roller combs

5. Productivity Before the Cotton Gin

6. Productivity After the Cotton Gin 50

7. The Rest of the Story… EW had a patent for his invention…but… The cotton gin was easy to duplicate Farmers made their own machines EW and his lawyers spent years traveling the South suing and losing… Increased use of slaves on plantations

8. Interchangeable Parts Product made the same way each time Identical parts in each product Workers specialize in their one task Broken parts are easy to replace

9. Life Before Whitney’s Inventions Slaves had to clean cotton by hand… slow and painful work…expensive Muskets and pistols were custom made…one at a time…expensive

10. Whitney’s Inventions Change Life Introduced the concept of mass production to American business Saved businesses time and money Increased productivity of slaves on plantations and factory workers Increased profits

11. Long-term Effects in the South Increased settlement of western lands Increased production of cotton Increased need for slaves to work the cotton fields Increased desire to remove Indians from prime land

12. Long-term Effects in the North Development of the textile industry Increased need for factory workers Growth of cities Increased trade with European countries
