Daniel Brendon Carroll DSC (17 November 1892 – 5 August 1956) was an Australian national representative rugby union player as well as an America rugby union player. He was a dual Olympic gold medalist winning in rugby at the 1908 Summer Olympics for Australia and also winning gold for the United States at the 1920 Summer Olympics. He later coached the gold-medal winning USA Rugby team at the 1924 Summer Olympics. He is erroneously referred to in some records as the youngest ever Australian representative rugby player due to a birthdate error in the Olympic records database. He served in the American Army as a Lieutenant in World War I and lived out his life in the USA working in the mining/petroleum industry.
He played for All-America against the All Blacks in 1913, a Test won by NZ 51-3. He served in the American Army as a Lieutenant in World War I and won a Distinguished Service Cross.
He completed a degree in geology at Stanford University in 1920 and was coaching rugby at the university when he was selected as the playing coach of the USA side selected for the 1920 Summer Olympics. He won a gold medal at Antwerp in that team playing at fly-half. He made three rugby union Test career appearances for the United States between 1913 and 1920.
Daniel Carroll passed away on August 6, 1956, in New Orleans, LA.
