Elijah McCoy: Inventor and Engineer
-
His first invention was a lubricator for steam engines. The invention allowed machines to remain in motion while being oiled; his new device revolutionized the industrial machine industry. McCoy established his own firm and was responsible for a total of 57 patents. The term "the real McCoy" refers to the oiling device used for industrial machinery. His contribution to the lubricating device became so popular that people inspecting new equipment would ask is the device contained the real McCoy. This helped popularize the American expression, meaning the real thing.
