Even today it is difficult to reconstruct Johanna Löwenherz’s biography in full. She was born on March 12, 1857 in Rheinbrohl and according to her biographer, Wolfgang Dietz, was “the daughter of a well-to-do Jewish family and brought up in the Jewish faith” (Dietz 1989, 31). Her father, Hermann Löwenherz (1811–1897), was a businessman who owned a quarry. Her mother was Fanni, née Jacobsohn (1826–1902). Little is known about her education, though Cornelia Kunze claims that she studied piano and singing at the Conservatory in Stuttgart and was able to teach Esperanto. Although by upbringing she was closest to the middle-class women’s movement, she switched to the socialist women’s movement, on whose behalf she traveled widely in order to raise consciousness. According to Dietz, this change in her political allegiance led her to abandon Judaism. She was one of the most active representatives of the Social Democratic Party (SDP) in the Neuwied region and co-founder of the local Volksbildungsverein (Association for Popular Education). Although her political opinions made her a somewhat controversial figure in the SDP, she was nevertheless elected as a delegate to the regional party conferences in Duisburg (1895), Essen (1897) and Neuweid (1897).
