Rietze was born in
Berlin-Köpenick. A metal worker by profession, he was at first a member of the
German Metal Workers' Union and then joined the
Revolutionäre Gewerkschafts Opposition. He was a member of the
Communist Party of Germany (KPD) from 1930, and also active in the workers' sports club "Nordwest". When the
Nazi Party came to power in 1933, Rietze continued working for the underground KPD. On 29 January 1934 he was arrested by the
Gestapo and interned in
Columbia concentration camp; Rietze was sentenced to three years' imprisonment on 1 November 1934, which he served in
Luckau prison. After his release, Rietze joined the resistance group around
Robert Uhrig. However, he was arrested again on 4 February 1942 and spent more than two years in
Sachsenhausen concentration camp before being tried and sentenced to death by the
People's Court on 6 July 1944. He was executed by guillotine on 28 August 1944 in
Brandenburg-Görden Prison. A street in the
Prenzlauer Berg borough of Berlin, Rietzestraße, was named after Rietze on 30 January 1952. ==References==
