The archive and library (approx. 50,000 objects) are the foundations of the museum's work. Our collection focuses on the literary journalism of the Weimar Republic, especially the world stage, books and testimonies of contemporaries as well as biographical and scientific literature on Kurt Tucholsky. The collection includes all of Kurt Tucholsky's first editions, an extensive collection of photographs and a reconstruction of his library. Special collections include the biographical collections on Kurt Tucholsky's first wife Else Weil, the poets Armin T. Wegner and Erich Arendt, and the natural scientist Alfred Wegener.
