Kästner, Ingrid2025-03-132025-03-1320241022-8012https://dspace.rsu.lv/jspui/handle/123456789/17167This article examines the transformative journey of scientific collaboration among Germany, the Baltic States, and Russia in the fields of medical history and natural sciences, following the geopolitical upheavals of 1990. The dissolution of the German Democratic Republic (GDR) and the unification of Germany disrupted long-standing academic partnerships with Eastern Europe, while simultaneously opening new avenues for collaboration. Focusing on the Karl Sudhoff Institute (KSI), the article highlights its pivotal role in navigating these changes. Despite significant challenges, including the loss of resources and personnel, the institute capitalised on its well-equipped library and extensive scholarly network to rebuild and strengthen ties with Eastern European academics. The narrative focusses on projects funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) concentrated on the history of medicine and natural sciences during the 18th and 19th centuries. These initiatives fostered scholarly dialogue among historians of medicine and researchers from Germany, Russia, Latvia, Estonia, Ukraine, and other countries through conferences, publications, and collaborative studies. Leveraging extensive archival materials, the projects addressed critical topics such as transfer of scientific ideas and evolution of institutional structures. By emphasising the broader implications of these collaborations, the article demonstrates how historical scholarship transcends geopolitical boundaries, fostering cultural and scientific cohesion. The study underscores the enduring value of international partnerships in advancing the understanding of medical history and promoting mutual intellectual engagement, even amidst shifting political contexts.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/medical historythe Baltic StatesRussiaGermanyresearch fundingscientific projectsArticle10.25143/amhr.2024.XVII.04
