Joseph Kruk (Hebrew: יוסף קרוק, December 5, 1885 in Częstochowa – July 6, 1972 in Jerusalem) was a socialist and Jewish-nationalist activist from his youth in Russia and Poland, where he played a political role between-the-wars.
Kruk took part in founding the first labour Zionist grouping in his hometown Częstochowa prior to the Russian Revolution of 1905.
When the revolution broke out, he was a major leader of the territorialist Zionist Socialist Workers Party in the city.
[1][2] Kruk, after a short episode in post revolution Russia, returned to Poland in 1918 and settled down in Warsaw.
Kruk was a member of the executive between June 1928 and October 1930, sharing the seat with the Yugoslav socialist leader Živko Topalović (like Drobner had done as well).
