Yitzhak was born in Petah Tikva in 1921 to Rahamim and Esther, who made aliya from Persia during WW1 for religious and nationalist reasons. The family had seven children. When he was five the family moved to Jerusalem and settled in Zichron Yoseph near Mahane Yehuda. The father had a grocery store and the mother was a housewife, raising the seven children with much dedication. Yitzhak studied at Doresh Zion religious school and at 14 learned hairdressing to enable him to contribute to the family income. He was a trainee studying and working in a barbershop for several years. Friends influenced him to join Beitar. Later aged 18 he joined Lehi and put up posters and distributed campaign material, even in the barbershop where he occasionally influenced youngsters to join Lehi.
After several years he opened his own barbershop on Yelin Street in Jerusalem. Among his many customers were young Arabs from Sheikh Jerach who sold him weapons that he gave Lehi, often paying for them with his own money. Among his customers and friends were Yoseph Abu-Gosh and other Arabs from his village. Following an anti-British attack and suspecting that the barbershop was connected to Lehi, British soldiers destroyed the place. They also found Lehi posters there and sent Yitzhak to Latrun Prison for several months. At the time his brother Daniel was also imprisoned for distributing Etzel posters. After their release Daniel, too, joined Lehi.
Yitzhak continued his Lehi activities in the Talbiye Base in Jerusalem for as long as was needed and even gave away his motorbike to Dror, the Base commander, for official use. He also gave haircuts to all the Lehi members in the base.
After the Bernadotte assassination he was arrested and imprisoned in Acre, then transferred to Jalame Prison where he spent nine months. After his release he joined the IDF and served in the Eilat Fort as barber and cook.
In 1952 he married his neighbor Batiya Nuriel who worked as a clerk in the Ministry of Trade and Industry. In 1956 they moved to North Tel Aviv, opened a barbershop, and both of them worked extremely hard.
They have four children – two daughters and two sons who are all married and have raised their families in Israel, and thirteen grandchildren. In 1980 he retired. Two of their children continue running the barbershop.
Yitzhak is one of the active members of the Ohel Israel Synagogue in North Tel Aviv. He serves as a committee member and secretary of the synagogue and devotes much of his time to the activities there.
