Aarhus → Gestapo Files: Grethe Bartram – Denmark’s Most Infamous Wartime Informer
Born 23 February 1924 in Aarhus into a poor communist family, Grethe Bartram (née Jensen) grew up in hardship. When Nazi Germany occupied Denmark on 9 April 1940, she was just 16.
While the vast majority of Danes either quietly resisted or joined the active resistance movement, Grethe chose collaboration.
At age 18 (1942) she began passing information to the Danish police, and soon directly to the Gestapo. Over the next three years she denounced more than 53 people — neighbours, friends, resistance members, and even her own family:
Her brother, Niels Jensen
Her fiancé/husband, Frode Thomsen
Numerous comrades from the communist youth group she once belonged to
Her reports led to arrests, brutal interrogations, and deportation to German concentration camps. At least eight of those she betrayed never returned; most died in Neuengamme, Stutthof, or other camps.
In 1944 the Danish resistance sentenced her to death in absentia and attempted to assassinate her (the bomb injured her but she survived and continued informing).
After liberation in May 1945, Grethe Bartram was arrested. The subsequent trial (1946–1947) became one of the most publicized in Danish legal history.
She was found guilty of assisting the enemy and causing the deaths of Danish citizens and initially sentenced to death — only the second woman in modern Danish history to receive that penalty. In 1948 the sentence was commuted to life imprisonment, later reduced. She was released in 1956.
Upon release she was expelled from Denmark and resettled in Sweden under a new identity. She lived quietly in the Malmö area until her death on 26 January 2017 at age 92, never having expressed public remorse.
Grethe Bartram remains the most reviled collaborator in Danish wartime memory — a stark reminder that betrayal can come from within families and communities, and that the moral choices made under occupation still echo today.
