Ryan Dahn is a historian of the natural sciences who studies the interaction between scientists and the state, primarily in 20th-century Germany. As a Beckman Center short-term fellow at the Institute, his research will focus on the newly acquired Bredig collection, tracing how early twentieth century networks of scientific communication were transformed in the 1930s into escape routes for Jewish scientists fleeing Nazi Germany.

Dahn received his PhD in conceptual and historical studies of science from the University of Chicago in 2019. Before coming to the Institute he was a fellow in residence at the Consortium for History of Science, Technology and Medicine. His research has been published in the leading history of science journal Isis. Dahn has previously received support from the German Academic Exchange Service (DAAD), the Max Planck Institute for the History of Science, and the Central European History Society.
