During the mid-1920s and the 1930s in Germany, Hannah Karminski served as secretary of the League of Jewish Women and, from 1924 to 1938, as editor of its newsletter. After the forced liquidation of the League in 1938, Karminski remained in Germany and continued her work in the Reich Association of Jews in Germany, assisting with the kindertransports and welfare. She was deported to Auschwitz and murdered in 1942.
