The Berliner Kammerbrettl was a cabaret founded after World War II by Hans Joachim Heinrichs at Café Wiesner near the Berlin S-Bahn station Ostkreuz. It paid special attention to the raw Berlin humor as well as critical, contemporary parody and satire. Initially, Heinrichs performed only with the impersonator and sketch partner Otto John in short programs. The well-known humorist Fredy Sieg then shone alongside Lotte Partyka and Ilse Maybrid in his first cabaret revue "Is There Still Love?" (1947). In his studio programs, Heinrichs not only presented young talents but also made efforts to promote a contemporary repertoire. Notable artists included Gerhard Froboess, Trude Lehmann, Hans Lugerti, and Ursula Müller.
