He studied with Legat and was engaged as the first Finnish ballet master of the Helsinki Suomalainen Opera (1921–35), the beginnings of the Finnish National Ballet. His first production was Swan Lake (1922). In 1935 he relocated to France where he worked with Fokine and the Ballets Russes de Monte Carlo, also in Paris at the Folies-Bergère. From 1939 to 1945 he was ballet master of the Royal Swedish Ballet. He returned to Helsinki in 1955 to become ballet master of the Finnish National Ballet for a second time, a post he held until his death. One of his most noted achievements was the reconstruction of Fokine's L'Épreuve d'amour.
