“The Real McCoy”

Elijah J. McCoy (May 2, 1844[2] – October 10, 1929) was a black 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 moved as a young child with his family to the United States in 1847, where he lived for the rest of his life and became a U.S. citizen.
Elijah J. McCoy was born free in 1844 in Colchester, Ontario, Canada to George and Mildred (Goins) McCoy, who were black. 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.
In Michigan, McCoy could find work only as a fireman and oiler at the Michigan Central Railroad. In a home-based machine shop in Ypsilanti, Michigan McCoy also did more highly skilled work, such as developing improvements and inventions. He invented an automatic lubricator for oiling the steam engines of locomotives and ships, “Improvement in Lubricators for Steam-Engines” (U.S. Patent 129,843).
Similar automatic oilers had been patented previously; one is the displacement lubricator, which had already attained widespread use and whose technological descendants continued to be widely used into the 20th century. Lubricators were a boon for railroads, as they enabled trains to run faster and more profitably with less need to stop for lubrication and maintenance.[3]
McCoy continued to refine his devices and design new ones; 50 of his patents dealt with lubricating systems. After the turn of the century, he attracted notice among his black contemporaries. Booker T. Washington in Story of the Negro (1909) recognized him as having produced more patents than any other black inventor up to that time. This creativity gave McCoy an honored status in the black community that has persisted to this day. He continued to invent until late in life, obtaining as many as 57 patents. Most of these were related to lubrication, but others also included a folding ironing board and a lawn sprinkler. Lacking the capital with which to manufacture his lubricators in large numbers, he usually assigned his patent rights to his employers or sold them to investors. Lubricators with the McCoy name were not manufactured until 1920, near the end of his career. He formed the Elijah McCoy Manufacturing Company to produce his works.[3]
Historians have not agreed on the importance of McCoy’s contribution to the field of lubrication. He is credited in some biographical sketches with revolutionizing the railroad or machine industries with his devices. Early twentieth-century lubrication literature barely mentions him; for example, his name is absent from E. L. Ahrons’ Lubrication of Locomotives (1922), which does identify several other early pioneers and companies of the field.
The popular expression “The real McCoy,” was first known to be published in Canada in 1881, however the linguistically similar “The Real McKay” can be traced to Scottish advertising in 1856. In James S. Bond’s The Rise and Fall of the “Union club”: or, Boy life in Canada, a character says, “By jingo! yes; so it will be. It’s the ‘real McCoy,’ as Jim Hicks says. Nobody but a devil can find us there.”[4]
This expression, typically used to mean the real thing, has been associated with Elijah McCoy’s oil-drip cup invention. One theory is that railroad engineers’ looking to avoid inferior copies would request it by name,[5] and inquire if a locomotive was fitted with “the real McCoy system”.[6][7] This possible origin is mentioned as a legend in Elijah McCoy’s biography at the National Inventors Hall of Fame.[8]
The original publication of this claim can be traced to the December 1966 issue of Ebony, in an advertisement for Old Taylor publishes the claim, ending in this tag line: “But the most famous legacy McCoy left his country was his name.”[9] The claim was repeated in a 1985 pamphlet printed by the Empak Publishing Company, which did not explain the origin of the expression.[10] The attribution has been disputed, and other origin stories exist for the phrase.
