He made his debut in 1926 in Den Haag as Nando in Tiefland. The same year, he went to Germany: Koblenz first, then 
Wuppertal. In 1932, he went on to Düsseldorf for seven years, where he changed his 
repertory from lyrical to heroic.
  The peak of his career seems to have been his Walther von Stolzing at
  the 1937 Salzburg Festival under Toscanini's baton; in 1935 and 1937, he also gave two guest performances as Radamès at the 
Vienna Staatsoper. From 1939 to 1944, he was a member of the Deutsche Oper Berlin and appeared also in Amsterdam. After the  
war, his career didn't get along very 
	well, and he ended up as a member of the small theatre of Münster. His 1952 stage farewell took place in 
Stuttgart.
	During WWII, he made 
	recordings for Odeon that were never released and are considered lost;  
	his voice is preserved in the Salzburg Meistersinger live recording under Toscanini, in a second act Meistersinger 
from the Berlin radio (1942), and in a 1936 radio 
recording of a cantata by the Dutch conductor and violinist Nico Treep.
