The Natzler family was of Jewish origin. Following
Hitler seizing absolute power in
Germany in March 1933 and the start of anti-Semitic legislation, Grete and Lizzi were offered increasingly fewer roles in films and stage performances in Germany. Grete had renounced her Jewish faith in 1930. She moved to the UK in 1934 and went to Hollywood on a one-year contract with
Paramount in 1935. By 1937 she had achieved minor celebrity as a film star and singer, had taken the stage name Della Lind, and was better known to an American audience as '
MGM's exotic Viennese singing actress'. Lizzi left Berlin to return to Vienna in 1933, but Austria experienced a similar political radicalization as Germany. Particularly during 1936–1937, which in 1938 resulted in Austria's
Anschluss with Germany. Jewish people were increasingly barred from the positions they held in Austria's society. Lizzi's last film role was in ''Heut' ist der schönste Tag in meinem Leben'', which was shot in 1935 and released in May 1936. Hertha's last performance in Vienna was in the
Femina Revue in March 1936. She was unemployed when she renounced her Jewish faith in April 1937. Together with Lizzi and her mother Lilly, Hertha left Austria and traveled to Rotterdam, from where they took the Dutch SS Statendam to New York in August 1937. Their destination was Hollywood and its film industry, where Grete was acting in several films, such as the
Laurel and Hardy film
Swiss Miss (1938). They arrived in October 1937. It appears that Hertha and Lizzi did not land any film roles in Hollywood. == Marriage to Frank Leddy, 1938–1945 ==
