Niels Rasmus Ib Birkedal Hansen (17 October 1909 – 20 July 1950) was a high-ranking Danish Nazi who acted as a chief in the Gestapo during the Second World War.
Notorious for his interrogation techniques, which involved torture and murder, he became a feared and reviled figure among members of the Danish resistance movement.
[2] After graduating from high school in 1924, he worked as a sailor for some time before trying his hand at a number of professions, most of which ended in failure.
After liberation, Hansen was sought throughout Europe and eventually apprehended in Germany in 1947, the last of the Birkedal Group who was still on the run.
During his trial, Hansen tried to plead insanity, and during observations at the infirmary at Vestre Prison, his actions grew increasingly peculiar.
