As the theatre was spared bombing damage during World War II, the theatre re-opened promptly on 25 April 1945 with "Dreimäderlhaus". In 1948, Rudolf Marik took over as director for almost 30 years, transforming it into an internationally recognised theatre of the German-speaking world exclusively staging operettas with stars such as Johannes Heesters, Marika Rökk, and others. Many well-known actors started their careers at the Raimund Theatre, including Hansi Niese, Paula Wessely, Attila Hörbiger, and Karl Skraup. After 1976 the theatre was occasionally used for musicals, such as Kurt Weill's "Lady in the Dark".
