Father of Rudolf

The father of Rudolf Heidemann was Hermann Heidemann (born 1892 in Berlin). Hermann was killed in WW I 1916 on the "Westfront". I am still searching his last address in Berlin, where we - my wife Maya Mosler-Heidemann and me - want to put up a memorial-stone ("Stolperstein") for him and his wife Hendrika de Wilde. Rudolf`s younger brother Günther died on 27th of December 1944 in Haiflingen near Stuttgart after surviving Auschwitz. There will be a memorial ceremony in Haiflingen for him and 300 other Jews on June 28th this month.
