Personal profile


I am a Danish historian who does research in intelligence services, surveillance history and military homing pigeons. My focus is predominantly on the first half of the 20th century and the two world wars.

I earned my PhD in history from the University of Copenhagen in 2021 on the thesis: The Threat to Democracy: Telesurveillance in Denmark, 1916-1945.
