Etymology

named for Edward Stanley, 12th earl of Derby (a county and town in England)

Word Origin

The first horse race called a Derby was named after an English nobleman named Edward Stanley, the Earl of Derby (1752–1834). The Earl instituted the race in 1780, and it continues to be run to the present day on the first Wednesday in June at Epsom Downs, a racetrack south of London. The name Derby has become attached to other races usually restricted to three-year-old horses, such as the Kentucky Derby. It is used as well of races that have nothing to do with horses, such as the Pinewood Derby run by the Cub Scouts. In the 1800s derby was also the name given in the U.S. to a dome-shaped hat called a bowler in England. The reason why the hat was given this name is uncertain, and nothing seems to link it with horse races.
