We are independent historians and art provenance researchers based in Germany and Poland whose collaborations were set in motion by the Holocaust Art Restitution Project (HARP), the German Lost Art Foundation, and the European Shoah Legacy Institute (ESLI). Our specialty is the Nazi era and its lasting ramifications. Since 2014 we have tenaciously traced people, private archives and looted property through twenty-five countries. In collaboration with legal counsel, we are ready to serve as agents in fact before Germany’s new Court of Arbitration for Nazi-looted Cultural Property.
