Tzvi came from an ultra-orthodox family and was one of seven siblings. He studied in several yeshivot. In the late 1930’s he distanced himself from religion and joined the “Hashomer Hatzair” movement. In the summer of 1943 he arrived in Budapest at the Zöldmáli hostel for apprentices. He learned metal engraving. He ran various errands for the underground. At the end of April 1944 he received his mobilization orders for a forced labor unit. He was equipped with forged documents which he hid, when necessary, in a loaf of bread. In July, while on holiday, he escaped, lived under a false name and was active in the underground, and crossed the border to Romania.
In 1945 he made aliya. He was among the settlers of Kibbutz Gvulot. In 1961 he moved to Kibbutz Ha’ogen where he is still a member. About one hundred of his relatives perished in the Holocaust. His brother, Piri, and his sister, Tzippi (Efra Agmon’s wife) made aliya and were members of Kibbutz Ha’ogen. Another sister, Esther Vardi, is also a member of Kibbutz Ha’ogen.
