The Bielski Brothers: The True Story of Three Men Who Defied the Nazis, Built a Village in the Forest, and Saved 1,200 Jews is a non-fiction book by Peter Duffy, which was published in 2003.
 It tells the story of Tuvia Bielski, Alexander Zeisal Bielski(Zus), Aharon Bielski, and Asael Bielski, four Jewish brothers who established a large partisan camp in the forests of Belarus during World War II, and so saved 1,200 Jews from the Nazis.
 The book describes how, in 1941, three brothers witnessed their parents and two other siblings being led away to their eventual murders.
 The brothers fought back against Germans and collaborators, waging guerrilla warfare in the forests of Belarus.
 By using their intimate knowledge of the dense forests surrounding the towns of Lida and Novogrudek, the Bielskis evaded the Nazis and established a hidden base camp, then set about convincing other Jews to join their ranks.
 The Germans came upon them once but were unable to get rid of them.
 As more Jews arrived each day, a robust community began to emerge; a "Jerusalem in the woods".
 In July 1944, after some 30 months in the woods, the Bielskis learned that the Germans, overrun by the Red Army, were retreating back toward Berlin.
Emilie Schindler (22 October 1907 – 5 October 2001) was a Sudeten German-born woman who, with her husband Oskar Schindler, helped to save the lives of 1,200 to 1,700 Jews during World War II by employing them in his enamelware and munitions factories, providing them immunity from the Nazis.
 She was recognized as Righteous Among the Nations by Israel's Yad Vashem in 1994.
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist, spy, and member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories, which were located in occupied Poland and the Protectorate of Bohemia and Moravia.
 He is the subject of the 1982 novel "Schindler's Ark" and its 1993 film adaptation, "Schindler's List", which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, and dedication to save the lives of his Jewish employees.
Abraham Bankier (1910-1956) was one of the owners of the "Rekord" factory on Lipowa street in Cracow, Poland, that Oskar Schindler took over during World War II.
 Schindler then hired Bankier to manage the factory, which was renamed "Deutsche Emailwarenfabrik Oskar Schindler", "Emalia" for short.
 Bankier was able to leverage black market dealings with extra scrap metal to bring additional Jews to work at the factory, thereby giving them a reprieve and ultimately saving many lives.
Schindler's List is a 1993 American epic historical period drama film directed and co-produced by Steven Spielberg and scripted by Steven Zaillian.
 It is based on the novel "Schindler's Ark" by Australian novelist Thomas Keneally.
 The film relates a period in the life of Oskar Schindler, an ethnic German businessman, during which he saved the lives of more than a thousand mostly Polish-Jewish refugees from the Holocaust by employing them in his factories during World War II.
 It stars Liam Neeson as Schindler, Ralph Fiennes as SS officer Amon Göth, and Ben Kingsley as Schindler's Jewish accountant Itzhak Stern.
Mieczysław "Mietek" Pemper (24 March 1920 – 7 June 2011) was a Polish-born Jew and a Holocaust survivor.
 Pemper helped compile and type Oskar Schindler's now-famous list, which saved 1,200 people from being killed in the Holocaust during World War II.
Assia Wevill (15 May 1927 – 23 March 1969) was a German-born woman who escaped the Nazis at the beginning of World War II and emigrated to Mandate Palestine, then later the United Kingdom, where she had a relationship with the English poet Ted Hughes.
 She killed herself and her four-year-old daughter Alexandra Tatiana Elise (nicknamed "Shura") in a fashion similar to that of Sylvia Plath, well-known writer and Hughes's first wife, who six years earlier had also committed suicide, by use of a gas oven.
The Schindlerjuden, literally translated as "Schindler's Jews", were roughly 1,100 Jews who were saved by Oskar Schindler during the Holocaust.
 They survived the years of Nazi regime primarily through the intervention of Schindler who found them protected status as industrial workers at his enamelware factory in Krakow and, after 1944, at an armaments factory in occupied Czechoslovakia.
 They avoided being sent to death camps and survived the war.
 Schindler expended his personal fortune as an industrialist to save the Schindlerjuden.
Erika Rosenberg (born 24 June 1951 in Buenos Aires, Argentina) is an author, interpreter and journalist.
 She wrote a biography of Emilie Schindler.
Leopold "Leo" Rosner (26 June 1918 – 10 October 2008) was a Polish-born Australian Jewish musician.
 Rosner survived the Holocaust in Nazi concentration camps during World War II by playing his accordion for Nazi guards and officials, earning the attention of Oskar Schindler who likely saved his life.
 His survival story became known after Australian author Thomas Kenneally's 1982 novel, "Schindler's Ark", was adapted into Steven Spielberg's Oscar-winning film, "Schindler's List".
 He appeared in the epilogue of the film at the Schindler memorial in Yad Vashem, Israel.
