Perl was a protégé of the
Revisionist Zionist movement of
Vladimir Jabotinsky. He participated in the movement during the 1930s as it became increasingly active against the
NSDAP. In 1938 he organized "
Die Aktion," a circle of young Viennese Zionists dedicated to making
Theodor Herzl's dream of an independent Jewish state a reality. Less than a year later, Die Aktion succeeded in landing a number of Jewish immigrants on the coast of then
Mandatory Palestine (now
Israel). This is believed to have been the first successful landing of such refugees, when almost every other escape route had been closed to them. Perl continued to work with Zionist groups and Greek smugglers, organizing large-scale illegal immigration of Jews to Palestine (
Aliyah Bet) and prodding reluctant Jewish leaders into doing the same. Perl rescued an estimated forty thousand Jews from
Nazi occupied Europe, often acting just one step ahead of the
Gestapo and of the British agents working to stop illegal immigration. ==Marriage and immigration to the United States==
