Inventor, Elijah McCoy (May 2, 1844 – October 10, 1929) Was a Canadian-American inventor and engineer, notable for his 57 U.S. Patents, most to do with lubrication of steam engines. The popular expression, "The real McCoy", was first published in Canada in 1881, but the expression, "The Real McKay", can be traced to Scottish advertising in 1856. This expression, typically used to mean the real thing, has been associated with Elijah McCoy's oil-drip cup invention.
African-American inventor Elijah the Real McCoy was born in Canada on May 2, 1844, the son of escaped slaves. During his life time McCoy received 57 patents for devices which improved versions of his automatic lubrication process. The high quality of McCoy's inventions gained such notoriety that the phrase "the Real McCoy" was coined to distinguish his inventions from cheap imitations.
