He hunted Jews, Roma, and the “asocial” for the Nazi regime — yet in July 1944, this same man secretly joined the plot to kill Adolf Hitler.
Arthur Nebe, head of Nazi Germany’s Criminal Police and commander of Einsatzgruppe B, personally oversaw the massacre of tens of thousands during the Holocaust and helped pioneer the use of gas vans for mass murder. But when Germany’s downfall seemed inevitable, he sided with the conspirators of the 20 July Plot — a failed attempt to assassinate Hitler.

Caught between fanaticism and betrayal, Nebe fled, faked his own death, and was finally hanged with a meat hook at Plötzensee Prison in 1945.
Once hailed as a patriot, today he is remembered as both executioner and opportunist — a man with blood on his hands who turned against the monster he helped build.
