Celebrating Elijah McCoy

Today’s Doodle celebrates the birthday of Elijah McCoy, a Black Canadian-American engineer and inventor who revolutionized train efficiency with his inventions. He held 57 patents in his lifetime, most of which were related to locomotives and railways.

In 1837, McCoy’s parents bravely escaped a life of enslavement in Kentucky through the Underground Railroad and sought freedom in Canada. Elijah was born in Colchester, Ontario and returned to the U.S. with his family at a young age. He grew up with a passion for problem-solving, mechanics, and trains. At age 15, he decided to further his education in the field and moved to Edinburgh, Scotland to become a mechanical engineer apprentice. 

Upon his return, McCoy settled in Michigan as opportunities to find work in Canada were very limited. In 1866, Black Americans faced rampant racial discrimination, which made finding a job that aligned with his level of experience in mechanical engineering extremely difficult. He joined the Michigan Central Railroad as a fireman and oiler, and quickly identified how inefficient it was to have to stop trains every few miles in order to manually lubricate their engines.

Six years into his role, McCoy addressed this issue by inventing what was colloquially known as an “oil-drip cup.” The cup caused oil to steadily flow around the engine without needing to stop the train. Consequently, McCoy obtained his first patent, “Improvement in Lubricators for Steam Engines.” Future variations  of his invention were later used to revolutionize oil-drilling and mining equipment along with construction and factory tools.

 McCoy continued to design new inventions while working as a consultant to engineering companies, including patents for a lawn sprinkler and ironing board. He eventually founded the Elijah McCoy Manufacturing Company in 1920, which produced lubrication devices displaying his name.

In 2001, Elijah McCoy was inducted into the National Inventors Hall of Fame in Akron, Ohio and has a dedicated exhibit in the Detroit Historical Museum. McCoy’s innovations and ingenuity kept trains chugging and have laid the tracks for the well-oiled machines of today. 

Happy birthday, Elijah McCoy!
