Prof. Hans-Jürgen Bömelburg (born 1961) is a historian of German-Polish and Central-Eastern European relations from the 16th to the 20th century. He currently teaches at the Justus-Liebig University in Gieβen. He is co-chairman of the German-Polish Handbook Commission and president of the Warmia Research Society. He also works closely with the Centre for Historical Research of the Polish Academy of Sciences in Berlin. Thanks to the kindness of Prof. Bömelburg, we are making some of his texts available in our "Repertorium academicum" collection.
