The war widow Anna Fisch, an active KPD member from 1923, took part in resistance activities after 1933. In particular, she offered persecuted communists shelter in her home in Berlin-Johannisthal. According to her own statements, she was denounced on several occasions by a neighbor and interrogated by the Gestapo.
In the summer of 1943, Anna Fisch took in Felix Luxenburg, a Jew living in hiding, for around a year. After another denunciation, she was arrested on August 27, 1944, and transferred to Fehrbellin “labor education camp” run by the Potsdam Gestapo branch. She was accused of various things, including listening to foreign radio stations. Her help for Felix Luxenburg presumably remained undiscovered.
In November 1944, Anna Fisch was admitted to Ravensbrück concentration camp, where she stayed until the camp was evacuated. She managed to escape from a death march of prisoners near Röbel an der Müritz. Her house in Johannisthal had been looted and burned down during her time in imprisonment.
