As second director, Pappenheim was also a member of the Association of German Natural Science Museums and served as its treasurer from 1928 to 1936. Because of his paternal “
non-Aryan” ancestry, he was pressured by the
Reich Ministry of Science, Education and Culture to voluntarily retire. He requested dismissal and was officially relieved of his directorial duties on 9 November 1938. However, he retained his curatorial post to support his family financially. == Politics ==
