Zarah Leander (German pronunciation: [ˈt͡sa.ʁa leː.ˈʔan.dɐ] ; 15 March 1907 – 23 June 1981) was a Swedish singer and actress whose greatest success was in Germany between 1936 and 1943, when she was contracted to work for the state-owned Universum Film AG (UFA). Although no exact record sales numbers exist, she was probably among Europe's best-selling recording artists in the years prior to 1945. Her involvement with UFA caused her films and lyrics to be identified as Nazi propaganda.
