Feldman (born July 18, 1959) was born in Tel Aviv after his father, Avraham, had immigrated to Israel from Europe after his entire family was murdered in the Holocaust. Tzvi's name is derived from Avraham's father.
Following completion of his required army service, Feldman worked as a nature guide for high school groups and had been accepted to university the fall before the First Lebanon War broke out. He and his girlfriend were considering marriage.
On June 11, 1982, in a battle with Palestinian and Syrian forces near the Lebanese village of Sultan Yaqub, five Israeli soldiers went missing. While two have since been returned to Israel, three others - Zachary Baumel, Yehuda Katz and Feldman- are still considered missing in action.
Since their abduction, Palestinian and Syrian officials have been unhelpful in providing Israel with any information about its missing soldiers.
