Michael Millowitsch, her great-great-great grandfather, had created a successful puppet theatre in Cologne as far back as the late eighteenth century.
Other films in which she appeared included Trenck, der Pandur (Tremck, the Squaddie, 1940), Komödianten ("Comedians"), 1941), Mein Leben für Irland ("My Life for Ireland", 1941) and Das große Spiel ("The Big Game", 1942).
[6] The Millowitsch Theatre was less badly damaged by Anglo-American bombing during World War II than other city venues, and on 16 September 1945 it was re-opened, at the express request of Mayor Konrad Adenauer : "Die Leute sollen wieder wat zu lachen haben!".
[2][a] The Millowitsch siblings who had formally taken over responsibility for running the theatre, relaunched the venue by staging Das Glücksmädel (loosely, "The Lucky Lass").
It was the first time a stage production had been broadcast on German television, and across West Germany it brought nationwide recognition to the theatre and to the company.
[8] Despite a focus on regional diversification, between 1949 and 1990 Cologne was, by many criteria, the most important and largest home to the West German television network: since 1953 more than 100 plays have been transmitted from the city's Millowitsch Theatre, many of them received with critical and public acclaim.
In particular, she became a frequent, visitor to Venezuela, engaging in efforts to improve conditions for ethnic groups who would have been identified in Germany at that time as "indigenous Indians".
[2][12] After the death of her husband Lucy Haubrich-Millowitsch increasingly redirected her attention away from the theatre, despite still being one of West Germany's most popular television actresses.
