Werner Naumann (16 June 1909 – 25 October 1982) was State Secretary in Joseph Goebbels' Ministry of Public Enlightenment and Propaganda during the Third Reich.
 He was appointed head of the Propaganda Ministry by Führer Adolf Hitler in his political testament after Dr. Goebbels was promoted to "Reichskanzler".
 Naumann was present in the "Führerbunker" in Berlin in late April 1945.
Goebbels: A Biography is a 2015 book by Peter Longerich.
 The book presents an account and analysis of the life of Nazi propaganda minister Joseph Goebbels, with extensive material from his diary which he kept from 1923 to 1945.
 It is an English translation of the 2010 German book "Goebbels: Biographie" by Longerich.
Johanna Maria Magdalena "Magda" Goebbels (née Ritschel; 11 November 1901 – 1 May 1945) was the wife of Nazi Germany's Propaganda Minister Joseph Goebbels.
 A prominent member of the Nazi Party, she was a close ally, companion and political supporter of Adolf Hitler.
 Some historians refer to her as the unofficial "First Lady" of Nazi Germany, while others give that "title" to Emmy Göring.
Bernard Julius Otto Kuehn (sometimes referred to as Kuhn) was a sleeper agent in the employ of the Abwehr for Nazi Germany who had close ties to Propaganda Minister Joseph Goebbels.
 In 1935, Goebbels offered Kuehn a job working for Japanese intelligence in Hawaii; he accepted and moved his family to Honolulu on August 15, 1935.
 The family included Dr. Kuhn, a pleasant scholarly man of 41; his wife, Friedel; a daughter, Susie Ruth (at 17, she was the former mistress of Goebbels); and her two half-brothers, Hans Joachim, and Eberhard.
Ralf Georg Reuth (born 4 June 1952 in Oberfranken) is a German journalist and historian.
 Reuth studied with Andreas Hillgruber and wrote his Ph.D. on the German strategy in the Mediterranean from 1940 to 1942.
 He published several books dealing with the Nazi era, among them a biography of Joseph Goebbels in 1992 and of Hitler in 2003.
 Reuth also edited a multivolume selection from the diaries of Joseph Goebbels, which drew criticism notably from Bernd Sösemann.
 He also wrote biographies of Erwin Rommel, Angela Merkel and Helmut Kohl.
The Goebbels children were the five daughters and one son born to Nazi propaganda minister Joseph Goebbels and his wife Magda Goebbels.
 The children, born between 1932 and 1940, were murdered by their parents in Berlin on 1 May 1945, the day both parents committed suicide.
Aleksandar Maćašev (] ), born in 1971, is a Serbian artist and designer known for his controversial Joseph Goebbels (TM) project in which Joseph Goebbels was depicted as the father of contemporary media culture.
Marie Noe (born August 23, 1928) is an American woman who was convicted in June 1999 of murdering eight of her children.
 Between 1949 and 1968, eight of the ten Noe children died of mysterious causes which were then attributed to sudden infant death syndrome.
 All eight children were healthy at birth and were developing normally.
 Two other children died of natural causes.
 Noe pleaded guilty in June 1999 to eight counts of second-degree murder, and was sentenced to 20 years' probation and psychiatric examination.
The Goebbels Diaries are a collection of writings by Joseph Goebbels, a leading member of the German Nazi Party (NSDAP) and the Reich Minister of Public Enlightenment and Propaganda in Adolf Hitler's government from 1933 to 1945.
 The diaries, which have only recently been published in full in German and are available only in part in English, are a major source for the inner history of the Nazi Party and of its twelve years in power in Germany.
 The British historian Ian Kershaw wrote in the preface to his biography of Hitler: "For all the caution which must naturally be attached to Goebbels's regularly reported remarks by Hitler ... the immediacy as well as the frequency of the comments makes them a vitally important source of insight into Hitler's thinking and action. "
The Vorbunker (upper bunker or forward bunker) was an underground concrete structure originally intended to be a temporary air-raid shelter for Adolf Hitler and his guards and servants.
 It was located behind the large reception hall that was added onto the old Reich Chancellery, in Berlin, Germany, in 1936.
 The bunker was officially called the "Reich Chancellery Air-Raid Shelter" until 1943, when the complex was expanded with the addition of the "Führerbunker", located one level below.
 On 16 January 1945, Hitler moved into the "Führerbunker".
 He was joined by his senior staff, including Martin Bormann.
 Later, Eva Braun and Joseph Goebbels moved into the "Führerbunker" while Magda Goebbels and their six children took residence in the upper "Vorbunker".
 The Goebbels family lived in the "Vorbunker" until their deaths on 1 May 1945.
