Leontine Sagan's Mädchen in Uniform (1931) is a groundbreaking German film that showcases women's agency and desire behind and in front of the camera. Adapted from Christa Winsloe's lesbian play, the story follows Manuela, who, after the death of her mother, is sent to a harsh Prussian boarding school. When Manuela declares her love with her female teacher, the oppressive principal punishes her, leading to a desperate suicide attempt. Barbara Mennel's compelling study firmly establishes Mädchen in the Weimar cinema canon. Mennel contextualises the film in 1920s theories of sexuality and the conventions of modernist cinema. She contrasts its international success to the extensive censorship battles that surrounded it. Mädchen's unique transnational and fragmented history results from the exile of many of its makers during the Nazi regime. By attending to the film's varied remakes throughout the twentieth and twenty-first centuries, Mennel underscores it's timeless impact that continues to resonate with contemporary audiences.
