I am a Ph.D. student at the Department of History of Humboldt-Universität zu Berlin and member of the research project “The London Moment”. I studied history and political science in Freiburg and Montreal as well as North American Studies at Freie Universität Berlin. My master thesis dealt with transnational networks in international family planning and population control after World War II, and was awarded with the Prize of the Department of History and Cultural Studies for Gender Studies. I received my master’s degree in 2015. In my Ph.D. project, I will follow up on my fascination with transnational collaboration in the twentieth century and turn towards the little-known International Commission for Penal Development and Reconstruction, located in Cambridge and London. Early in the Second World War, this informal network brought together eminent jurists from occupied countries as well as Great Britain. They discussed war crimes trials and the internationalization of humanitarian law and yielded some of the legal innovations that later shaped the Nuremberg Trials.
