[3] In 1888, when she was thirty-seven, Hanna married the lawyer Richard Bieber (born 1858), whom she had met while studying in Berlin.

[1] After her marriage Hanna Bieber Böhm remained a member of the Association of Berlin artists, but her painting became a secondary activity as she became interested in politics.

[2] Germany under chancellor Prince Otto von Bismarck was growing both economically and in population, and various associations and clubs had been formed to address social issues.

Bieber-Böhm became involved in the movement fighting for women's rights, which was concerned with morality, prostitution, protection of children and other issues.

[1] The Jugendschutz educated young Germans on the virtues of temperance and chastity, taught them to shun places of lax entertainment and to avoid promiscuity and alcoholicism, vices that she saw as closely connected.

Other German delegates were Auguste Förster, Elisabeth Kaselowsky, Agnes Burchard, Annette Hamminck Schepel, Marie Fischer-Lette and Käthe Schirmacher.

[5] In 1894, representing Jugendschutz, she participated in foundation of the Bund Deutscher Frauenvereine (BDF: Federation of German Women's Associations) in Berlin.

The location was quiet and far from Berlin, and was used as a vacation home for girls in poor health, mothers with children and older women.

[6] In Germany there was fierce debate among feminists about how to handle prostitution, seen as the source of venereal diseases and thus a major health problem.

Pappritz proposed moral education of young people and encouragement of abstinence outside marriage, while Stocker thought that giving women more sexual freedom would eliminate the demand for prostitution.

However, after the 1891 Heinze trial[b] provoked moral outrage, Bieber-Böhm gained support from feminists for her petition to the parliament of Germany entitled "Suggestions for the Fight against Prostitution".
