Adolf Hitler killed himself by gunshot on 30 April 1945 in his "Führerbunker" in Berlin.
 His wife Eva Braun committed suicide with him by taking cyanide.
 That afternoon, in accordance with Hitler's prior instructions, their remains were carried up the stairs through the bunker's emergency exit, doused in petrol, and set alight in the Reich Chancellery garden outside the bunker.
 Records in the Soviet archives show that their burnt remains were recovered and interred in successive locations until 1970, when they were again exhumed, cremated, and the ashes scattered.
The "Führer" Headquarters ("Führerhauptquartiere" in German), abbreviated FHQ, is a common name for a number of official headquarters used by the Nazi leader Adolf Hitler and various German commanders and officials throughout Europe during the Second World War.
 Perhaps the most widely known headquarters was the "Führerbunker" in Berlin, Germany, where Hitler committed suicide on 30 April 1945.
 Other notable headquarters are the "Wolfsschanze" (Wolf's Lair) in East Prussia, where Claus von Stauffenberg in league with other conspirators attempted to assassinate Hitler on 20 July 1944, and Hitler's private home, the "Berghof", at Obersalzberg near Berchtesgaden, where he frequently met with prominent foreign and domestic officials.
Ferenc Szálasiné (née Gizella Lutz or "Lucz"; 21 October 1906 – 1992) was the longtime companion and, for a brief time, wife, of Ferenc Szálasi who served as Leader of the Hungarian Nation and "de facto" Prime Minister of Hungary at the end of the Second World War.
 They were married on 29 April 1945, on the wedding day of Adolf Hitler and Eva Braun.
 She was captured by the United States Army on 3 July 1945 and transferred to Hungary.
 Her husband was executed on 12 March 1946.
 She was sentenced to twelve years imprisonment on 3 December 1953.
 She was released in 1958.
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.
Ewald Lindloff (27 September 1908 – 2 May 1945) was a Waffen-SS officer during World War II, who was present in the "Führerbunker" on 30 April 1945, when Hitler committed suicide.
 He was placed in charge of disposing of Hitler's remains.
 Lindloff was later killed during the break-out on 2 May 1945 while crossing the Weidendammer Bridge under heavy fire in Berlin.
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.
The last will and testament of Adolf Hitler was prompted by Hitler receiving a telegram from "Reichsmarschall" Hermann Göring asking for confirmation of Göring's succession, combined with news of Heinrich Himmler's attempted negotiations of surrender with the western Allies, and reports that Red Army troops were within a block or two of the Reich Chancellery.
 It was dictated by Adolf Hitler to his secretary Traudl Junge in his Berlin "Führerbunker" on 29 April 1945, the day he and Eva Braun married.
 They committed suicide the following day, 30 April, two days before the surrender of Berlin to the Soviets on 2 May, and just over a week before the end of World War II in Europe on 8 May.
 It consisted of two separate documents, a will and a political testament.
During the final weeks of the Third Reich and the war in Europe, many civilians, government officials and military personnel throughout Nazi Germany committed suicide.
 Aside from high-ranking Nazi officials like Adolf Hitler, Joseph Goebbels, Heinrich Himmler, Philipp Bouhler and Martin Bormann, many others chose " Selbstmord" (German: "Self-murder" ) rather than accept the defeat of Germany.
 Studies have shown that the suicides were influenced through Nazi propaganda (reaction to the suicide of Adolf Hitler), the tenets of the Nazi Party, and the anticipated reprisals following the Allied occupation of Nazi Germany.
 For example in April 1945, at least 1,000 people killed themselves and others within 72 hours as the Red Army neared the East German town of Demmin.
Conspiracy theories about Adolf Hitler's death contradict the fact that Adolf Hitler committed suicide in his "Führerbunker" on 30 April 1945.
 Most of these theories hold that Hitler and his wife, Eva Braun, survived and escaped the city of Berlin.
 While subject to some exposure in popular culture, examples being books such as "Grey Wolf: The Escape of Adolf Hitler", these viewpoints are regarded by mainstream historians as disproven fringe theories.
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.
