Nathan Schwalb (left) was the head of the He-halutz international bureau in Geneva, Switzerland, during the war. As early as 1941, he had attempted to convince the Jewish leadership in Berlin to organize escape routes. Throughout the war, Schwalb organized support for He-halutz groups in German-occupied Europe. One of those groups was “Chug Chaluzi” in Berlin, which was led first by Jizchak Schwersenz (right) and later by Gad Beck. These photos show Schwalb and Schwersenz after Schwersenz’s escape in early 1944, and Schwalb and his colleagues from the He-halutz bureau.
