Wladyslaw Szpilman (Adrien Brody) survives the war thanks to a German officer who spared his life, gave him food and let him stay hidden in the attic of that house. The German officer (and the rest of his men) are sent to a Russian prison camp. Szpilman goes back to playing piano and unfortunately, never learns the name of the officer who saved his life. The name of the officer is Wilm Hosenfeld. Wilm Hosenfeld died in a Soviet prison in 1952. He was posthumously awarded the Yad Veshem's title of "Righteous Among Nations" in October 2007. Szpilman was not the only Jew he saved during WWII.
