She was born on 13 July 1876 in
Piešťany. Her father Karl Ludwig Zwerenz (1850–1925) was an actor and director, as well as director of theaters in
Bolzano,
Merano, Bucharest,
Teplice,
Jihlava,
Pressburg and
Bad Hall. Her mother, Eveline Zwerenz (1842–1921), worked at the Stadttheater in
Baden bei Wien from 1888 to 1891 and 1893 to 1903. Her grandfather Karl Zwerenz (1826-1898) and her great-grandfather
Karl Ludwig Costenoble were Hofburg actors. At first, she did not want to follow in the footsteps of the family. Then she followed the tradition, took lessons and made her debut in Baden bei Wien. She played in
Bielitz, at the summer theater in
Mödling, toured with the Wiener Soubrettenensemble in Russia, in
Friedrich-Wilhelmstädtischen Theater in Berlin and sang between 1901 and 1920 in the
Carltheater in Vienna. There she starred as Helena in the original 1913 production of
Oskar Nedbal's hit operetta
Polenblut in which she had a tremendous success. At the Viennese Apollo-Theater, Zwerenz was a major force. In the early 1920s, she ran the
Mizzi Zwerenz establishment in Baden, for which she collaborated with popular actors (including
Fritz Imhoff). In addition to her stage work, she appeared in several films, including
Die kleine Veronika (1929) and
Walzer um den Stephansturm (1935). Mizzi Zwerenz died of a heart condition on 14 June 1947 in Vienna. She is buried at the city's
Hietzing Cemetery (group 29, number 9). Zwerenz married actor Arthur Guttmann (1877-1952), brother of the twins
Emil and
Paul Guttmann, in 1905. She retired from the stage in 1937. Their son, Fritz Zwerenz (3 September 1895 in Vienna; 12 October 1970 in Linz), was successful, sometimes supporting his mother's artistry as a Kapellmeister in the field of music theater. After World War II, he worked mainly as a concert conductor and at the radio station
Radio Linz. ==Notes==
