In 1929, he went back to Berlin, where Cornelis Bronsgeest, a famous Dutch baritone, engaged him for a radio broadcast as Vasco da Gama in Meyerbeer's L'Africaine. This was the beginning of a successful international career. Owing to his diminutive stature (he was just over 1.5 m, or 4' 11") a stage career was impossible; however his voice was extremely well suited for radio. He made many records, first for Ultraphone, then for Odeon/Parlophone, was featured in many radio broadcasts and acted in several movies in both German and English.
