'''Elijah J. McCoy''' (May 2, 1844{{hsp}}{{efn-ua |Sources give his birthdate as May 2, 1843; May 2, 1844; or less commonly March 27, 1843.}} &ndash; October 10, 1929) was a Canadian-American engineer of [[African Americans|African-American]] descent who invented [[lubrication]] systems for [[steam engine]]s.  Born free on the [[Ontario]] shore of [[Lake Erie]] to parents who fled [[History of slavery in Kentucky|enslavement in Kentucky]], he traveled to the United States as a young child when his family returned in 1847, becoming a U.S. resident and citizen. His inventions and accomplishments were honored in 2012 when the [[United States Patent and Trademark Office]] named its first regional office, in [[Detroit, Michigan]], the "Elijah J. McCoy Midwest Regional Patent Office".<ref>{{cite news |title=It's the real McCoy: First patent office outside of D.C. to open in Detroit |url=https://www.michiganradio.org/auto/2012-01-11/its-the-real-mccoy-first-patent-office-outside-of-d-c-to-open-in-detroit |access-date=2 May 2022 |work=Michigan Radio (NPR) |date=11 January 2012 |language=en |archive-date=12 May 2022 |archive-url=https://web.archive.org/web/20220512015724/https://www.michiganradio.org/auto/2012-01-11/its-the-real-mccoy-first-patent-office-outside-of-d-c-to-open-in-detroit |url-status=live }}</ref>

==Early life==
Elijah McCoy was born in 1844 in [[Colchester, Ontario]], to George and Mildred Goins McCoy. At the time, they were [[fugitive slave]]s who had escaped from [[Kentucky]] to Ontario via helpers through the [[Underground Railroad]].<ref>{{Cite book|last=Marshall|first=Albert|title=The "real McCoy" of Ypsilanti|date=1989|publisher=Marland Pub.|location=Ypsilanti, MI|asin=B002O5L4XG}}</ref> George and Mildred arrived in Colchester Township, Essex County, in what was then called [[Upper Canada]] in 1837 via [[Detroit]]. Elijah McCoy had eleven siblings. Ten of the children were born in Ontario from Alfred (1836) to William (1859).

Upper Canadian schools were [[Racial segregation#Canada|segregated]] under the Common Schools Act as amended in 1850,<ref>{{cite web|url=http://www.ohrc.on.ca/en/issues/racism/racepolicydialogue/ccs|title=Tuition Fee Increases and the History of Racial Exclusion in Canadian Legal Education|at=Racial Discrimination in Legal Education: A Brief History|first=Charles C|last=Smith|date=December 2004|website=Ontario Human Rights Commission|archive-url=https://web.archive.org/web/20120417033053/http://www.ohrc.on.ca/en/issues/racism/racepolicydialogue/ccs|archive-date=2012-04-17|url-status=dead}}</ref><ref>{{Cite canlaw|short title  =An Act for the better establishment and maintenance of Common Schools in Upper Canada|abbr =S.Prov.C.|year =1850|chapter = 48|section=19|link= https://books.google.com/books?id=CFQ1AQAAMAAJ&lpg=PA1421&ots=aqOMGZeekt&pg=PA1263#v=onepage&f=false}}</ref> and McCoy was educated in black schools of Colchester Township. At the age of 15, in 1859, Elijah McCoy was sent to Scotland. While there he was apprenticed and, after studying at the [[University of Edinburgh]], certified as a [[Mechanical engineering|mechanical engineer]].<ref>{{cite web |title=Elijah McCoy (1844–1929) |url=https://www.ed.ac.uk/alumni/services/notable-alumni/alumni-in-history/elijah-mccoy |website=The University of Edinburgh |date=21 July 2015 |access-date=2 May 2022 |language=en |archive-date=2 May 2022 |archive-url=https://web.archive.org/web/20220502162738/https://www.ed.ac.uk/alumni/services/notable-alumni/alumni-in-history/elijah-mccoy |url-status=live }}</ref> Based on 1860 Tax Assessment Rolls, land deeds of sale, and the 1870 US Census it can be determined George McCoy's family moved to [[Ypsilanti, Michigan]] in the United States in 1859–60; by the time Elijah returned, his family had established themselves on the farm of John and Maryann Starkweather in Ypsilanti. George used his skills as a [[tobacconist]] in order to establish a tobacco and cigar business.{{citation needed|date=May 2022}}

==Career==
When Elijah McCoy arrived in Michigan, he could find work only as a [[Fireman (steam engine)|fireman]] and [[oiler (occupation)|oiler]] at the [[Michigan Central Railroad]]. In a home-based machine shop in Ypsilanti, 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" ({{US patent|129843}}).

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 [[Rail transport|railroads]], as they enabled trains to run faster and more profitably with less need to stop for lubrication and maintenance.<ref name=National/> By 1899, the [[Michigan Department of Labor and Economic Opportunity|Michigan Bureau of Labor and Industrial Statistics]] reported that the McCoy lubricator was in use on almost all North American railroads.<ref name="MichiganBLS">{{cite journal |last1=Owens |first1=A.

McCoy continued to refine his devices and design new ones, and was noted in periodicals of the time, including the [[Railroad Gazette]].<ref name="railroadGazette">{{cite news |author1=S. Wright Dunning |author2=M. N. Forney |author2-link=Matthias N.

After the turn of the century, he attracted notice among his [[African Americans|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 related to lubrication, but others also included a folding [[ironing board]] and a [[Irrigation sprinkler|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. In 1920, near the end of his career, he formed the Elijah McCoy Manufacturing Company.<ref name="DetroitHistorical">{{cite web |title=McCoy, Elijah |url=https://detroithistorical.org/learn/encyclopedia-of-detroit/mccoy-elijah |website=Encyclopedia of Detroit |publisher=[[Detroit Historical Society]] |access-date=2 May 2022 |archive-date=2 May 2022 |archive-url=https://web.archive.org/web/20220502162150/https://detroithistorical.org/learn/encyclopedia-of-detroit/mccoy-elijah |url-status=live }}</ref>

==Regarding the phrase "The real McCoy"==
{{Main|The real McCoy}}

This popular expression, typically meaning ''the real thing'', has, among other sources, been attributed to Elijah McCoy's oil-drip cup invention. The theory was that railroad engineers looking to avoid inferior copies would request it by name,<ref name="MIT">{{cite web |url=http://web.mit.edu/invent/iow/mccoy.html |archive-url=https://web.archive.org/web/20030823125258/http://web.mit.edu/invent/iow/mccoy.html |url-status=dead |archive-date=2003-08-23 |title=Elijah McCoy, Inventor of the Week |publisher=[[Jerome H.

== Marriage and death ==
McCoy married for the second time in 1873 to [[Mary Eleanora Delaney]]. The couple moved to [[Detroit]] when McCoy found work there.

==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."<ref name="old-taylor-advertisement" />
*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]]<ref name="casselman"/> 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 2001 novel ''[[Noughts & Crosses (novel series)|Noughts & 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".<ref>{{cite book|last=Blackman|first=Malorie|title=Noughts & Crosses|location=New York|publisher=[[Random House]]|date=2001}}</ref>
*A 1945 song by [[Richard Rodgers]] and [[Oscar Hammerstein II]], "Isn't it Kinda Fun", from the musical ''[[State Fair (musical)|State Fair]]'', includes the lyrical phrase "...this is the real McCoy."
