Tzvi grew up in a traditional Jewish family in Érsekújvár (Nové Zámky) in Czechoslovakia. He joined the “Hashomer Hatzair” movement at an early age. In 1942 Tzvi was enlisted in a forced labor unit and sent to Ukraine. Because he fell sick with typhus, he was sent back to Gyør in Hungary. In the fall of 1944 an emissary of the Zionist underground arrived in Gyør with a bag full of forged documents for members of “Hashomer Hatzair”, “Dror” and “Maccabi Hatzair” who were serving in the camp. Tzvi ran away from the camp and, together with his friend, Anti (Dan Livni) arrived in Budapest. Both of them joined the underground activities. As a member of the staff of the International Red Cross, Tzvi went to the Protected Houses and the ghetto to help the Jews by giving them Swiss Protection Documents and food. Tzvi also escorted the ‘Rudi Bácsi’ carts. While in hiding on Wekerle Sándor Street, he forged seals. After the liberation he took part in the organization of children’s houses. Tzvi was sent to Romania in order to set up transit stations for olim. For two and a half years he worked in Transylvania as the movement’s secretary. In July 1948 Tzvi arrived in Israel, joined the garin in Kibbutz Dan and later, in the framework of hashlama, he moved to Kibbutz Megiddo.
Tzvi was a member of Kibbutz Usha.
