Elijah J. McCoy (May 2, 1844〔Sources give his birthdate as May 2, 1843; May 2, 1844; or less commonly March 27, 1843.〕 – October 10, 1929) was an African Canadian-American inventor and engineer, who was notable for his 57 U.S. patents, most to do with lubrication of steam engines. Born free in Canada, he returned as a five-year-old with his family to the United States in 1847, where he lived for the rest of his life and became a US citizen. ==Early life== Elijah J. McCoy was born free in 1844 in Colchester, Ontario, Canada to George and Mildred (Goins) McCoy. They were fugitive slaves who had escaped from Kentucky to Canada via helpers through the Underground Railroad. In 1847, the family returned to the US, settling in Ypsilanti, Michigan. He had eleven siblings. At age 15, McCoy traveled to Edinburgh, Scotland for an apprenticeship and study. After some years, he was certified in Scotland as a mechanical engineer. After his return, he rejoined his family.
