Carl-Heinrich Rudolf Wilhelm von Stülpnagel (2 January 1886 – 30 August 1944) was a German general in the Wehrmacht during World War II who was an army level commander. While serving as military commander of German-occupied France and as commander of the 17th Army in the Soviet Union during Operation Barbarossa. Stülpnagel participated in German war crimes, including authorising reprisal operations against civilian population and cooperating with the Einsatzgruppen in their mass murder of Jews. He was a member of the 20 July Plot to assassinate Adolf Hitler, being in charge of the conspirators' actions in France. After the failure of the plot, he was recalled to Berlin and attempted to commit suicide en route, but failed. Tried on 30 August 1944, he was convicted of treason and executed on the same day.

Hans Paul Oster (9 August 1887 – 9 April 1945) was a general in the Wehrmacht and a leading figure of the anti-Nazi German resistance from 1938 to 1943. As deputy head of the counter-espionage bureau in the Abwehr (German military intelligence), Oster was in a good position to conduct resistance operations under the guise of intelligence work.
He was involved in the Oster conspiracy of September 1938 and was arrested in 1943 on suspicion of helping Abwehr officers caught helping Jews to escape Germany. After the failed 1944 July Plot on Hitler's life, during interrogation, he named Admiral Wilhelm Canaris, the head of Abwehr, as the "spiritual founder of the Resistance Movement". The Gestapo arrested Canaris and eventually found his diaries, in which Oster's anti-Nazi activities were revealed. In April 1945, he was hanged with Canaris and Dietrich Bonhoeffer at Flossenbürg concentration camp.

Theodor Haubach (15 September 1896 in Frankfurt am Main – 23 January 1945 in Berlin) was a German journalist, SPD politician, and resistance fighter against the Nazi régime.
Theodor Haubach spent his childhood and youth in Darmstadt. In 1914, right after his Abitur, he took part in the First World War as a volunteer, and was wounded repeatedly. After the horror of his wartime experiences, Haubach resumed studying.
From 1919 to 1923, he studied philosophy, sociology, and economics and eventually graduated. As of 1920, Haubach, like his friend Carlo Mierendorff, was an SPD member and worked together actively with the Young Socialists. From 1924 to 1929 he was editor of the newspaper Hamburger Echo, and later (1929-1933) an associate at the Reich Interior Ministry and with the Berlin Police President. From 1924 Haubach was the leading member of the Reichsbanner Schwarz-Rot-Gold, an association that campaigned fiercely for the Weimar democracy and actively struggled under the emblem of the "Three Arrows" against the Nazis, who were grasping for power.
Beginning in February 1933, Haubach, like many SPD members, was persecuted by the Nazi régime. After his first arrest in 1934, he was detained in Esterwegen concentration camp. From 1935, he worked as an insurance representative, and later established contacts with the Kreisau Circle. After the failed attempt on Hitler's life at the Wolf's Lair in East Prussia on 20 July 1944, Haubach was arrested and sentenced to death by the Nazi "People's Court" (Volksgerichtshof). Now very ill, Theodor Haubach was hanged on 23 January 1945 along with Helmuth James Graf von Moltke at Plötzensee Prison in Berlin.

Gerhard Marcks (18 February 1889 – 13 November 1981) was a German artist, known primarily as a sculptor, but who is also known for his drawings, woodcuts, lithographs and ceramics.

Otto Wilhelm Heinrich Wagener (29 April 1888 – 9 August 1971) was a German major general and, for a period, Adolf Hitler's economic advisor and confidant.

Rudolf Levy (15 July 1875, in Stettin – January 1944, in Italy or Auschwitz) was a German expressionist painter of Jewish ancestry.

Albert Günther Göring (9 March 1895 – 20 December 1966) was a German engineer, businessman, and the younger brother of Hermann Göring (head of the German Luftwaffe, founder of the Gestapo, and leading member of the Nazi Party). In contrast to his brother, Albert was opposed to Nazism, and helped Jews and others persecuted in Nazi Germany. He was shunned in post-war Germany because of his family name, and died without any public recognition, receiving scant attention for his humanitarian efforts until decades after his death.

Karl-Günther Heimsoth, also known as Karl-Guenter Heimsoth (4 December 1899, Charlottenburg – July 1934, Berlin), was a German physician, polygraph, and politician. Heimsoth was a member of the Nazi Party and later the Communist Party of Germany.

Victor Klemperer (9 October 1881 – 11 February 1960) was a German scholar who also became known as a diarist. His journals, published in Germany in 1995, detailed his life under the German Empire, the Weimar Republic, the Third Reich, and the German Democratic Republic.
The three volumes of his diaries have been published in English translations: I Shall Bear Witness, To the Bitter End, and The Lesser Evil. The first two cover the period of the Third Reich have since become standard sources and have been extensively quoted. His book Lingua Tertii Imperii, published in English as The Language of the Third Reich, studies how Nazi propaganda manipulated and influenced the German language.

Hans Benno Hüttig (5 April 1894 – 23 February 1980) was a German SS functionary and Nazi concentration camp commandant.
