Social Democratic Party of Germany politicians

Ernst Torgler (25 April 1893 – 19 January 1963) was the last chairman of the Communist Party of Germany (KPD) faction in the German Reichstag before he worked for the Nazis.

Frieda Rosenthal (born Frieda Schrinner: 9 June 1891 – 15 October 1936) was a Berlin local politician and, after 1933, active in resisting the Nazi régime. Concerned that, under interrogation, she had inadvertently implicated a fellow activist, she died by hanging herself, using a radiator, in her prison cell.

Max Fechner (27 July 1892 – 13 September 1973) was a German politician who served as Minister of Justice of East Germany from 1949 to 1953

Hulda Martha Arendsee (29 March 1885 – 22 May 1953) was a German politician (KPD) and women's rights activist.

Hilde Radusch (6 November 1903 – 2 August 1994) was a German political activist (KPD, SPD) who became involved in anti-fascist resistance. As the 20th century progressed, she became increasingly prominent as a feminist and lesbian activist.Throughout her life Radusch kept a diary. Accessed by researchers after she died, her own writings have provided an insightful, and at times engagingly laconic, commentary on her eventful life.

Herta Geffke (married name, Herta Kaasch: 19 August 1893 – 29 December 1974) was a German activist and politician (KPD, SED) who resisted Nazism. After 1945 she became a member of the Party Central Control Commission (Zentrale Parteikontrollkommission / ZPKK) in the Soviet occupation zone (from 1949 the German Democratic Republic), identified as a "true Stalinist" and feared on account of her interrogation methods.

Carl Legien (1 December 1861 – 26 December 1920) was a German unionist, moderate Social Democratic politician and first President of the International Federation of Trade Unions.

Ernst Heilmann (13 April 1881 – 3 April 1940) was a German jurist and politician of the Social Democratic Party of Germany.

Born in Berlin, then in Prussia, Heilmann attended the University of Berlin and majored in law and political science.
During the First World War, Heilmann was a proponent of the German party truce (Burgfriedenspolitik). He gained a seat in the Reichstag in the 1928 German federal election. Not long after Hitler and the Nazis seized power (Machtergreifung), Heilmann was arrested by the Gestapo and imprisoned in the first of a series of concentration camps in which he was to spend nearly seven years.From February 1937, Heilmann was kept in Dachau concentration camp until he was transferred in September 1938 to Buchenwald concentration camp, where he was executed in April 1940.

Irmgard Enderle (born Irmgard Rasch: 28 April 1895 – 20 September 1985) was a German politician, trade unionist and journalist.

Karl Grönsfelder (18 January 1882 – 20 February 1964) was a Bavarian political activist and politician (KPD).When the Communist party was briefly banned in 1923/24, his activism earned him a period in "protective custody" in June 1924. A longer period of detention followed the Nazi take-over in 1933. After 1945 Grönsfelder returned to political activism, despite being marginalised and expelled (not for the first time) from the Communist Party in 1949.
