Context: Joachim Ziegler (2 October 1904 – 2 May 1945) was a high-ranking commander in the Waffen-SS of Nazi Germany during World War II.  He was the commander of the SS Division Nordland, and was a recipient of the Knight's Cross of the Iron Cross with Oak Leaves. Hitler (1962) is a black and white American film (that was later re-released with the title, "Women of Nazi Germany").  The film stars Richard Basehart in the title role of Adolf Hitler.  Cordula Trantow stars as Geli Raubal and Maria Emo as Eva Braun.  John Banner stars as Gregor Strasser.  The film depicts Hitler through the years, beginning with the Beer Hall Putsch of November 1923 and focuses mainly on his private life, in particular, his relationships with niece Geli and longtime companion/wife, Eva Braun.  According to film critic and historian Leonard Maltin, Basehart "gives a cerebral interpretation" of Hitler during the timeframe he was the leader of Nazi Germany.  For her performance, Cordula Trantow was nominated for a 1962 Golden Globe in the category: Most Promising Newcomer - Female.  The film was produced by Three Crown Productions, Inc. and distributed by Allied Artists Pictures. SS-"Obersturmbannführer" Erich Kempka (16 September 1910 – 24 January 1975) was a member of the SS in Nazi Germany who served as Adolf Hitler's primary chauffeur from 1934 to April, 1945.  He was present in the area of the Reich Chancellery on 30 April 1945, when Hitler shot himself in the "Führerbunker".  Kempka delivered the gasoline to the garden behind the Reich Chancellery where the remains of Hitler and Eva Braun were burned. Hans Otto Georg Hermann Fegelein (30 October 1906 – 28 April 1945) was a high-ranking commander in the Waffen-SS of Nazi Germany.  He was a member of Adolf Hitler's entourage and brother-in-law to Eva Braun through his marriage to her sister, Gretl. Ilse Braun (1909 – 1979) was one of two sisters of Eva Braun.  Born in Munich, Ilse was the oldest daughter of school teacher Friedrich "Fritz" Braun and seamstress Franziska "Fanny" Kronberger.  She became the sister-in-law of Nazi dictator Adolf Hitler following his marriage to Eva on 29 April 1945, less than 48 hours before the couple committed suicide together on 30 April 1945. Eva Anna Paula Hitler ("née" Braun; 6 February 1912 – 30 April 1945) was the longtime companion of Adolf Hitler and, for fewer than 40 hours, his wife.  Braun met Hitler in Munich when she was a 17-year-old assistant and model for his personal photographer; she began seeing him often about two years later.  She attempted suicide twice during their early relationship.  By 1936, she was a part of his household at the Berghof near Berchtesgaden and lived a sheltered life throughout World War II.  Braun was a photographer, and many of the surviving colour photographs and films of Hitler were taken by her.  She was a key figure within Hitler's inner social circle, but did not attend public events with him until mid-1944, when her sister Gretl married Hermann Fegelein, the SS liaison officer on his staff. Karl Schümers (17 October 1905 – 18 August 1944) was a high-ranking commander in the Waffen-SS and Ordnungspolizei (police) of Nazi Germany during World War II.  He commanded the SS Polizei Division in July – August 1944.  He was directly or indirectly involved in many of the major during 1944.  Killed by a landmine on 18 August 1944, he was posthumously awarded the Knight's Cross of the Iron Cross. Karl Wolff (13 May 1900 – 17 July 1984) was a high-ranking member of the Nazi SS who held the rank of SS-"Obergruppenführer" in the Waffen-SS.  He became Chief of Personal Staff Reichsführer-SS (Heinrich Himmler) and SS Liaison Officer to Hitler until his replacement in 1943.  He ended World War II as the Supreme Commander of all SS forces in Italy.  In 1964, Wolff was convicted of war crimes in West Germany; he was released in 1969. Paul Hausser (7 October 1880 – 21 December 1972) was a high-ranking commander in the Waffen-SS of Nazi Germany during World War II who played a key role in the post-war efforts by former members of the Waffen-SS to achieve historical and legal rehabilitation. Margarete Berta "Gretl" Braun (31 August 1915 – 10 October 1987) was one of the two sisters of Eva Braun.  She was a member of the inner social circle of Adolf Hitler at the Berghof.  Braun married SS-Gruppenführer Hermann Fegelein, a liaison officer on Hitler's staff, on 3 June 1944.  Fegelein was shot for desertion in the closing days of World War II.  Gretl became the sister-in-law of the Nazi dictator following his marriage to Eva, less than 40 hours before the couple killed themselves together.
