Eli Whitney was the inventor of the cotton gin and a pioneer in the mass production of cotton. Whitney was born in Westboro, Massachusetts on December 8, 1765 and died on January 8, 1825. He graduated from Yale College in 1792. By April 1793, Whitney had designed and constructed the cotton gin, a machine that automated the separation of cottonseed from the short-staple cotton fiber. Eli Whitney's invention of the cotton gin revolutionized the cotton industry in the United States.
   In 1798, Eli Whitney invented a way to manufacture muskets by machine so that the parts were interchangeable. Ironically, it was as a manufacturer of muskets that Whitney finally became rich.

Paul Marie Eugène Vieille (2 September 1854 – 14 January 1934), a graduate of Ecole Polytechnique, was a French chemist and the inventor of modern nitrocellulose-based smokeless gunpowder in 1884. The new smokeless powder was three times as powerful as black powder for the same weight and left virtually no residues of combustion. Paul Vieille soon became director of the "Laboratoire Central des Poudres et Salpetres" in Paris where his research had taken place. His invention was applied not only to small arms but also to the full range of artillery ammunition. His invention was widely followed within a short time by all the major military powers. Vieille received the Prix Leconte (₣50,000) in 1889 in recognition of his discovery.
