Benjamin Robertson "Ben" Harney (March 6, 1872 – March 2, 1938) was an American songwriter, entertainer, and pioneer of ragtime music. His 1896 composition "You've Been a Good Old Wagon but You Done Broke Down" is regarded as one of the early ragtime composition. In 1924, the New York Times wrote that Ben Harney "probably did more to popularize ragtime than any other person." Time Magazine termed him "Ragtime's Father" in 1938.
Ben Harney is generally said to have been born in Louisville, Kentucky. Although some sources put his birthplace as Nashville, Tennessee, according to his father's military records he was born in Memphis, Tennessee. In the past some have claimed that Harney was African-American and early in his career he is said to have played with African American theater troupes. But, W.C. Handy correctly referred to him as "white". All photographic and contemporary accounts show that Harney was light skinned with red hair. He married and lived in white society and always represented himself as White. Furthermore his well-documented family background conclusively proves his ethnicity. Harney was the son of Benjamin Mills Harney, a veteran of both the Mexican-American War and the Civil War, and his second wife Margaret Wellington Draffin, daughter of a prominent Kentucky lawyer. His grandfather was John Hopkins Harney, the first mathematics professor at Indiana University and author of the first algebra textbook ever published in the United States. His uncle William Wallace Harney was a renowned journalist and author. And, he counted two prominent U.S. generals as distant cousins: Lew Wallace and William Selby Harney.
