After arriving in England, she became a featured soprano on BBC Radio in operas and operettas by Offenbach,[1] Lehar[2] and Horton[3] in the late 1930s. During WW2 she broadcast anti-Nazi German-language propaganda radio programs for BBC Europe which were heard across the Continent. After her husband died suddenly in 1949 from a heart attack, she remarried and moved to Saltdean on the Sussex coast in England.[citation needed] In the 1950s she continued broadcasting for BBC Radio, singing in operettas and recitals such as "The Queen of Song" about the life of Adelina Patti.[4] She also sang and spoke in German language educational radio programs for the BBC from 1938 onwards.[3]
