Haim was born in Nizhny Novgorod, Russia, on June 10, 1914 to Adele and Yehoshua. As a youth, a blood libel forced him, his parents and his brother Mordechai, to flee; among many other fugitives, they ended up settling in Lublin.
The father was traditional and a Zionist, teaching Hebrew and speaking it with his children at home. From a young age, Haim was active in Beitar and became a cell commander in Lublin and a command officer for the Lublin region. When the family moved to Otwock, he founded a cell and headed it.
He made aliyah with the Mapilim ship Parita, which arrived at the shores of Tel Aviv on August 22,1939 and he was detained in Sarafand. He was freed a week after World War II began. Haim was the only one in his family to survive the war. The parents died behind Soviet lines, where they had fled, while his brother Mordechai was murdered by local Poles upon returning to see what was left of the family’s possessions. Shortly after making aliyah, Haim married Esther Kalvir, whom he knew from Lublin and who had made aliyah four years earlier.
Haim joined Lehi in 1940, working in Department 6 in communications and fundraising. His home, at 59 HaYarkon, was an address for mail from abroad for Lehi, and two or three times a week it would be used to print underground material.
Once the State was established, Haim turned his energies to providing for his young family, taking whatever job he could. For 27 years, he was the administrative director of HaKirya Women’s and Maternity Hospital, retiring in 1979.
From his youth, Haim was interested in stamps and numismatics, both ancient and modern. He acquired vast knowledge, so much so that the hobby became his main means of support in retirement. His writings about stamps were collected in various newspapers, journals and periodicals, including HaMashkif, Herut, HaYom, Ha’aretz, Yedioth Ahronoth, HaTzofe and Globes. He received many prizes and awards, one of them from then-Finance Minister Dan Meridor.
Haim was active until his last day, serving as secretary of the union of Parita Mapilim. Shortly before his death, he was still writing. His fell ill suddenly and died a month later.
Haim died in Tel Aviv on August 18,1999.
He left behind his wife Esther, two daughters (Nili and Rivka), grandchildren and great-grandchildren.
