After enjoying considerable success in his native country, he relocated to Europe in 1932 and spent most of the rest of his life in France. He won twelve British Classic Races and two Prix de l'Arc de Triomphes. On his retirement in 1957 he was described as "one of the greatest international jockeys of modern times". He died of a heart attack in 1964.
