Elijah McCoy is a famous African American inventor. His first major invention was a lubrication for oiling the engines of locomotives and steamboats which he patented in July of 1872. He has obtained about 57 patents, all relating to lubricants, but also invented the folding ironing board and the lawn sprinkler. He is also associated with the saying, "the real McCoy", meaning, "the real thing", because railroad workers would inquire if their locomotive was fitted with "the real McCoy" rather than some inferior copy.
