Wilhelm Dreimann (1904–46) was deployed from the Hamburg police force in 1940 as a guard in Neuengamme Concentration Camp. He carried out executions in the camp single-handedly. Prisoners identified him as the executioner of Neuengamme. According to evidence from Frahm, he hanged at least the first two children and, with the help of Wiehagen and Frahm, also the adult prisoners. He was sentenced to death in the Curio-Haus trial and executed on 8 October 1946.
