Ernst Reinke (28 November 1891 –- 28 April 1943) was a German Communist activist who became a politician and, in 1930, member of parliament. After 1933 he went on to become a resistance activist. He spent his final years as a concentration camp inmate. Sources identify his 1943 killing by government paramilitaries at Camp Flossenbürg, in the mountains east of Nuremberg, as a murder.
