Alma Wartenberg  Wilhelmine Catharina Alma Wartenberg (born "Stähr"; * 22 December 1871 in Ottensen; died 25 December 1928 in Altona) was a member of the Social Democratic Party of Germany und Women's Rights Activists. Alma Wartenberg was born into a social democratic working class family with twelve children. She worked as a housemaid until she married the locksmith Ferdinand Wartenberg. They had four children  In Hamburg-Ottensen was crucially engaged in forming the proletarian women's movement. 1902 to 1906 she was elected every year on women's congresses as a social democratic delegate for the constituency Ottensen/Pinneberg. Asagitator amongst working women, Wartenberg toured through the North-German state of Schleswig-Holstein and participated in women's conferences and party conventions as a delegate. 1905 she initiated with others a campaign against the judgement of the Altona court to release four young and middle class men after they had been found guilty of the rape of a housemaid. During and after the campaign, Wartenberg supported a collaboration with the so-called "Radicals" of the middle class women's movement. This contradicted the official party policy and brought her in conflict with the party leadership. A procedure to expel her from the party was stopped. However, she was nonetheless forced to put down her responsibilities as a delegate. Being denied to continue working as a delegate for the party, Wartenberg took action especially for maternity protection, birth control and sexual education. High infant mortality rate, widespread „women's suffering“ due to many births, miscarriages and a large number of illegal abortions, lack of information to sexual issues and missing government support had alarmed her. Again, she toured the country, this time with pictured slide shows, to educate about female anatomy, contraception and mother protection. Her shows drew hundreds of listeners. After her show she publicly sold contraception, even though the "sale or transmission of hygienic rubber articles" was liable to prosecution in the German Empire. With this she didn't only antagonize the Empire's judiciary but also the association of doctors and especially ecclesiastic circles. Repeatedly she was prosecuted for „offense of public nuisance“. However, she insisted on every woman's right to decide over her body and number of births alone. Again in contradiction with official party policy, Wartenberg supported the idea of a „birthing strike“ that was controversially discussed within social democracy as a protest against the compulsion to give birth propagated by the state.
