Margaret Knight

Paper bag manufacturing

  • Can you imagine what grocery shopping would be like if you had to carry envelope-shaped paper bags?
  • She received her first patent when she was thirty for a machine that would make the square bottoms of paper bags.
  • She watched people hand make flat bottom bags and thought to herself "There has to be a way to make that happen with a machine."
  • She developed that idea and after a man tried to steal her idea, she won a court battle giving her the patent in 1870.
