Harry Joseph Costello (November 9, 1891 – August 24, 1968) was an American college football player and coach who later served as an officer in the Allied intervention in the Russian Civil War.
The son of Patrick Costello, he was born around 1892.[1]
He was an alumnus of Georgetown University, where he has been described as a "legendary quarterback."
Costello was a halfback selected for Outing magazine's "Football Honor List for 1911" picked by coaches from the East and West. The only other southern player on the list was Ray Morrison.
In 1912 Georgetown won the South Atlantic Intercollegiate Athletic Association (SAIAA) posting an 8–1 record with its only loss to 1912 Carlisle Indians football team under first-year head coach Frank Gargan. Nathan Stauffer of Collier's Weekly selected Costello as his All-Southern quarterback.[2] [3]
He was captain in his final season of 1913.[4]
Costello was the head football at the College of Detroit for the 1915 and 1916 seasons. His coaching record at Detroit was 4–7–2.[5]
Costello joined the United States Army and trained at Fort Sheridan. Elements of the 85th Infantry Division, including Costellos formation, went to Russia as part of the Allied intervention in the Russian Civil War, where they were stationed in Arkhangelsk.[6]
In 1957, he was living in Waterford, Virginia. He died in Washington, D.C. in 1968.
