The real McCoy was a black Canadian, born to escaped Kentucky slaves in Colchester, Ontario in 1843. Despite having studied engineering in Scotland, on his return to Canada, Elijah McCoy was unable to find any job other than as a railway fireman. As a mechanic in the 1870s, he noticed that machines had to stop every time they needed oil. Mr. McCoy invented a device to oil machinery while it was working, and soon no engine or machine was complete until it had a McCoy Lubricator.
