SS-Hauptsturmführer Hermann Hackmann (October 11, 1913 – August 20, 1994) was a Nazi German war criminal, SS captain in two extermination camps during World War II. He was a roll call officer at KL Buchenwald, and lead guard in charge of the so-called protective custody at Majdanek concentration camp in German-occupied Poland. Described as a brutal man with a cynical sense of humour, Hackmann was tried three times. The first time, he was prosecuted for murder and sentenced to death by SS Judge Georg Konrad Morgen in connection with the Koch trial. Hackmann escaped punishment and was evacuated by the Gestapo.
Hackmann came from Osnabrück. At the age of 26 he first assumed the post of SS officer at Buchenwald. After the war, Hackmann was prosecuted this time by the U.S. government at the Buchenwald Trial of 1947. He was one of twenty-two Nazis sentenced to death for his role in the crimes against humanity committed at Buchenwald, though the sentence was commuted to life imprisonment. Details of his activities in Buchenwald that surfaced during the trial portray him as a man who was greatly feared by the prisoners and prone to violence and using creative ways to put prisoners through torture. Inmates were frequently beaten, kicked and whipped by Hackmann with sticks and whips. He was also known to make prisoners kneel where he would kick them in the scrotum. There was a rule against spitting on the camp road and when Hackmann saw some spit on the ground he forced the nearest inmate to lick it up. One witness testified that he had two block leaders bend a birch tree where he made a Jewish man hold onto it. When the block leaders released the tree, the Jewish man was flung into the air into a stone quarry.
During the Third Majdanek Trial between 1975 and 1981, he was sentenced to an additional ten years imprisonment for two counts of serving as joint accessory to murder of at least 141 prisoners at KL Lublin / Majdanek concentration camp.
