Elijah J. McCoy
(May 2, 1844 – October 10, 1929)
was a Canadian born African American inventor and engineer who was notable for his 57 U.S.
patents,
most having to do with the lubrication of steam engines.
Born free in
Canada, he came to the United States as a young child when his family
returned in 1847, becoming a U.S. resident and citizen.
