Cotton Gin Cotton Gin American inventor, pioneer, mechanical engineer, and manufacturer Eli Whitney is best remembered as the inventor of the cotton gin. He also affected the industrial development of the United States when, in manufacturing muskets for the government, he translated the concept of interchangeable parts into a manufacturing system, giving birth to the American mass-production concept. Whitney saw that a machine to clean the seed from cotton could make the South prosperous and make its inventor rich. He set to work at once and within days had drawn a sketch to explain his idea; 10 days later he constructed a crude model that separated fiber from seed. After perfecting his machine he filed an application for a patent on June 20, 1793; in February 1794 he deposited a model at the . . . .
