This article situates the trajectory of the academic life of Seniha Tunakan (1908–2000) within the development of anthropology as a scientific discipline in Turkey and its transnational connections to Europe during the interwar period and up until the second half of the 20th century. Relying on the archives of the Max-Planck-Gesellschaft, the archive of the Humboldt-Universität zu Berlin, the Politisches Archiv des Auswärtigen Amtes in Germany, and the Prime Ministry's Republican Archives in Turkey, it focuses on the doctoral studies of Seniha Tunakan in Germany and her life as a female PhD researcher in the capital of the Third Reich, as well as her entire research career after her return to Turkey. Through Tunakan's career, the article also provides an analysis of the perpetuation of German race science in the Turkish context, shedding light upon the success of the Kaiser-Wilhelm-Institut für Anthropologie, menschliche Erblehre und Eugenik (Kaiser Wilhelm Institute for Anthropology, Human Heredity, and Eugenics) and its transnational impact.
