He was a mainstay of his country's Davis Cup team in the years immediately following World War II, helping them reach the Inter-Zonal final in successive years in 1947 and 1948, though they fell to Australia on both occasions. His biggest individual tournament victories in singles were his two Swiss International Championships in 1946 and 1950.
