He made first experiences with theaters on tour, later followed among others stage engagements in Kassel, Essen, Bochum, Berlin and Bromberg.
He also realised a movie as a director with "Bund der Sieben" (1933).
The actor Curt Lauermann grew up in a family which was dedicated to the acting. So he also became an actor both on stage and in movies.
Besides his activity as an actor he also wrote some screenplays for the movies "Der einzige Zeuge" (1922), "Der Wetterwart" (1923), "Motor, Liebe, Leidenschaft" (1925) and "Der König der Mittelstürmer" (1927).
He sometimes played a messenger and a typesetter, sometimes a court clerk or a crew member of an Atlantic giant, and after 1945 also more serious characters, but mainly (mostly in television productions) he continued to play the classic "little man from the street".
