In September 1933 the Swedish national socialist Malte Welin was appointed lecturer for Nordic literature at the Friedrich Wilhelms University in Berlin. Plans also existed to make him lecturer for Swedish at the same university and the lecturer Vilhelm Scharp was therefore dismissed. Welin himself lost the lectureship less than three months later without even having been in Berlin. This article describes and analyzes the „case Welin“ as an example for the attempt to adapt Nordic studies in Berlin to National Socialist politics. The appointment led to protests and a strain in Swedish-German relations. This is also analysed in detail.
