Elijah McCoy (1844 – 1929) – Lubricating cup for trains
Elijah McCoy never had to endure life in slavery thanks to the Underground Railroad, which helped his parents escape to Canada after being enslaved. At 15, McCoy enrolled in a boarding school in Edinburgh, Scotland, to study mechanical engineering. Despite his education, McCoy encountered difficulty finding respectable work in the United States, mainly due to racial discrimination.
He eventually secured a position as a fireman for a railroad company, where he was responsible for oiling the moving parts of the trains. The need for greater efficiency inspired McCoy to invent an automatic lubrication mechanism that reduced the need for labor and kept the train running smoothly. Some attribute the phrase “the real McCoy” to the success and efficiency of this mechanism, making it an expression of superior performance and quality.
