Rosey E. Pools networks for German-Jewish refugees in the 1930's

Lonneke Geerlings (doctorate graduate at VU University Amsterdam) employs network analysis in her research of Rosey E. Pool (1905-1971), a Dutch translator, educator and Black Poetry expert. In the 1930's, Pool helped German Jews escape from Berlin to the Netherlands and in the 1940's she got involved in the German-Jewish resistance group Van Dien in Amsterdam. As fellow of the European Holocaust Research Infrastructure (EHRI), Geerlings did research into Dutch-German contacts and exchanges. For this, she combines various historical and biographical sources in a network analysis, combined with intersectionality, to discover clusters.
