Wilhelm Adalbert Hosenfeld (German pronunciation: [ˈvɪl(hɛl)m ˈhoːzənfɛlt]; 2 May 1895 – 13 August 1952), originally a school teacher, was a German Army officer who by the end of the Second World War had risen to the rank of Hauptmann (Captain). He helped to hide or rescue several Polish people, including Jews, in Nazi-German occupied Poland, and helped Jewish pianist and composer Władysław Szpilman to survive, hidden, in the ruins of Warsaw during the last months of 1944, an act which was portrayed in the 2002 film The Pianist. He was taken prisoner by the Red Army and died in Soviet captivity in 1952.
