Elijah J. McCoy (May 2, 1844 – October 10, 1929) was a Canadian-American inventor and engineer of African descent who was notable for his 57 U.S. patents, most having to do with the 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 U.S. citizen.
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.
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, patenting it in 1872 as "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.
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.
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.
Regarding the phrase "The real McCoy"
This popular expression, typically meaning 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, and inquire if a locomotive was fitted with "the real McCoy system". This theory is mentioned in Elijah McCoy's biography at the National Inventors Hall of Fame. It can be traced to the December 1966 issue of Ebony in an advertisement for Old Taylor bourbon whiskey: "But the most famous legacy McCoy left his country was his name." A 1985 pamphlet printed by the Empak Publishing Company also notes the phrase's origin but does not elaborate. Other possibilities for its origin have been proposed.
Marriage and family
McCoy married Ann Elizabeth Stewart in 1868; she died four years later.
He married for the second time in 1873 to Mary Eleanor Delaney. The couple moved to Detroit when McCoy found work there. Mary McCoy (b. - d. 1922) helped found the Phillis Wheatley Home for Aged Colored Men in 1898.
Elijah McCoy died in the Eloise Infirmary in Nankin Township, now Westland, Michigan, on October 10, 1929, at the age of 86, after suffering injuries from a car accident seven years earlier in which his wife Mary died. He is buried at Detroit Memorial Park East in Warren, Michigan.
In popular culture
- 1966, an ad for Old Taylor bourbon cited Elijah McCoy with a photo and the expression "the real McCoy", ending with the tag line, "But the most famous legacy McCoy left his country was his name."
- 2006, Canadian playwright Andrew Moodie's The Real McCoy portrayed McCoy's life, the challenges he faced as an African American, and the development of his inventions. It was first produced in Toronto and has also been produced in the United States, for example in Saint Louis, Missouri, in 2011, where it was performed by the Black Rep Theatre.
- In her novel Noughts and Crosses, Malorie Blackman describes a racial dystopia in which the roles of black and white people are reversed; Elijah McCoy is among the black scientists, inventors, and pioneers mentioned in a history class that Blackman "never learned about in school".
- 1974, the state of Michigan put an historical marker (P25170) at the McCoys' former home at 5720 Lincoln Avenue and at his gravesite.
- 1975, Detroit celebrated Elijah McCoy Day by placing a historic marker at the site of his home. The city also named a nearby street for him.
- 1994, Michigan installed a historical marker (S0642) at his first workshop in Ypsilanti, Michigan.
- 2001, McCoy was inducted into the National Inventors Hall of Fame in Akron, Ohio.
- 2011, Senator Debbie Stabenow offered an amendment to the Patent Reform Act of 2011 to name the first satellite office of the U.S. Patent & Trademark Office, which opened in Detroit, Michigan, on July 13, 2012, as the "Elijah J. McCoy United States Patent and Trademark Office".
