They were in close contact, and she significantly assisted Weidt's effort to protect his employees by hiding Jewish women in her home and illegally trading for supplies.

When the situation ultimately became too dangerous, due to police raiding another apartment in the same building in mid-1943, the Bernstein twins relocated to Wilmersdorf while Porschütz' mother sheltered the other two women.

Otto Weidt's group sent more than 150 food parcels to Theresienstadt Ghetto to supply at least 25 people imprisoned there.

Due to her black market trade, Porschütz was sentenced to 18 months in prison in October 1944 by a Nazi Sondergericht.

Her requests to be compensated for political persecution and to be titled an "Unsung Heroine" were rejected by West Berlin authorities in 1959.
