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.

A cotton gin is a machine that quickly and easily separates cotton fibers from their seeds, allowing for much greater productivity than manual cotton separation.The fibers are processed into clothing or other cotton goods, and any undamaged cotton was used for clothes.he modern mechanical cotton gin was invented in the United States of America in 1793 by Eli Whitney (1765â1825).
