Wilhelm Hosenfeld (2 May 1895 – 13 August 1952), was a German Army officer who rose to the rank of Hauptmann by the end of the war. He helped to hide or rescue several Poles, including Jews, in Nazi-occupied Poland, and is perhaps most remembered for helping Polish-Jewish pianist and composer Władysław Szpilman to survive, hidden, in the ruins of Warsaw during the last months of 1944. He died in Soviet captivity on 13 August 1952, from injury possibly sustained during torture.
