The Pianist is a memoir in which the author survives with the help of which German Army officer?
Wilm Hosenfeld Wilhelm Adalbert Hosenfeld (] ; 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-occupied Poland, and helped Polish-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 seven years later.
Adalbert Dani von Gyarmata und Magyar-Cséke Adalbert Dani von Gyarmata und Magyar-Cséke (also sometimes spelled Magyarcseke; 26 May 1868—14 April 1920) was an officer of the Austro-Hungarian Army who served in World War I, holding a number of senior positions, including chief of staff of VI Corps, Army Group Tersztyanszky, and the 3rd Army. Before the conflict began, he had worked in Russia, China, and Japan as a military attaché, becoming an observer during the Russo-Japanese War. It was during that time that von Gyarmata became acquainted with John Pershing, who went on to command the American Expeditionary Force in Europe during the war.
