- On April 17, Prof. Haeberle was visited for the third time by his Japanese colleague Prof. Hiroyuki WAGATA from the university in Osaka, who returned to Berlin for several months of research at the Haeberle-Hirschfeld-Archiv. His main interest is the cultural context in which German sexology began and the relationship between  the German sexological pioneers, especially Hirschfeld, and their Japanese colleagues.
