Personal profile
Profile
I am a Danish historian specializing in the history of surveillance, intelligence services, policing, and military homing pigeons. My primary focus is on the first half of the 20th century, particularly the two World Wars.
My work delves into the everyday practices of surveillance and intelligence operations, exploring how these activities were concretely executed and embedded in broader societal and institutional contexts.
I am particularly interested in the history of technology, examining how new technologies create opportunities for innovation while simultaneously introducing new concerns, anxieties, and methods of surveillance. My research also investigates the tension between old and new technologies, revealing how traditional methods persist, adapt, or are replaced as technological landscapes evolve.
In 2021, I earned my PhD in History from the University of Copenhagen with the dissertation The Threat to Democracy: Telecommunications Surveillance in Denmark, 1916–1945. This work reflects my commitment to understanding how historical surveillance practices shaped - and were shaped by - their technological, cultural, and political environments.
