While Eli Whitney is best remembered as the inventor of the cotton gin, it is often forgotten that he was also the father of the mass production method. In 1798 he figured out how to manufacture muskets by machine so that the parts were interchangeable.

However, after Eli Whitney unveiled the cotton gin, processing cotton became much easier resulting in greater availability and cheaper cloth.
