Tzvi, son of Ida and Yitzhak, was born in 1911 in Kovno (Kaunas), Lithuania. From a young age, he and his family knew only suffering and wandering. World War I and the Bolshevik Revolution forced them to leave their home; eventually, they arrived in Rostov, where they stayed through the revolution and civil war. These events began to shape his worldview. When the family returned to Kovno, he began studying in the Jewish Gymnasium. He was also one of the founders of Beitar in Kovno.
He was very active in the movement, to which he dedicated all his energy and time. He was always accepted and beloved, the life of the party, creating an environment of happiness and productivity. In 1935, he made aliyah illegally and joined the Beitar company in Rosh Pina.
When he arrived in the Land of Israel, Tzvi was one of the founders of the Aqaba Development Company. His love for the land motivated him to learn to became a surveyor. He joined the IZL together with his underground friends, and he was stopped a number of times by the British. He was imprisoned in Jaffa, Jerusalem, Acre and Tzrifin.
After the split, in 1941, he moved on to Lehi. At the same time, he moved to Tel Aviv, working as a surveyor in the Mandatory surveying department, when the Hatikvah neighborhood was established. He forged deep connections with the Yemenite leaders of the neighborhood, and he worked among them with dedication and faithfulness. He was among the founders of the Aero Club of Israel. He wanted to train Jewish pilots to take part in the war against the Nazis. “He dreamed of flying a bomber over Berlin, but he died in an accident,” as an article commemorating thirty days since his passing put it (HaMashkif, January 10,1945).
He was one of the first to enlist in the British Army, in the Engineering Corps, out of the faith that this would teach Jewish youth the art of war. He was then transferred to a surveying unit and promoted to corporal. He was beloved by all his comrades, soldiers from Australia, who loved his temperament and his personality. When he was transferred to Egypt, he was in touch with Lehi members who planned and executed the assassination of Lord Moyne. As a military man, he could move freely between the Land of Israel and Egypt, which benefitted Lehi operations in both places. Among other duties, he was charged with making maps of northern Israel and Syria. He was part of the capture of Syria by the Allies. He then made his way to Egypt by way of Iraq, fighting all the way through the deserts of North Africa westward until Benghazi. He fought in the Battle of el-Alamein and was injured in his leg.
Tzvi served four years in the British Army. On December 6,1944 he was killed in a train accident in Egypt, next to Ismailia, and he was buried there. His comrades tried to get his body reinterred in Israel, but they were unsuccessful.
