Her engagement in the fight against prostitution sprang from the matrix of the shock she
experienced in encountering East European Jewry. Statistics prove just how serious this
problem was at that time in this milieu in Germany.
Since the 1880s, a high percentage of
the traffickers in girls, prostitutes, pimps and procurers, and female brothel owners were
Jews from Eastern Europe. This fact was ignored by male heads of the Jewish Communities
in Germany, since they believed this was a matter of personal weakness of character and
not a social phenomenon. To look the other way was in keeping with the moral canon of the
era. The Jewish public also feared that dealing with this problem and publication of figures
could be exploited by antisemitic propaganda as a characteristic that distinctively marked
the ‘Jewish race’.
In her view of East European prostitution, the problem of material poverty was fused with the
problem of an internal, spiritual and intellectual poverty that had to be comprehended in social terms, not merely as something individual.
