Yitzhak was born in Basra, Iraq, in 1930 to his parents Shoshana and Yaakov. His father made aliyah in 1931 for Zionistic reasons; once he was financially established, he brought back the rest of the family: his wife and four children. The family settled in Jerusalem. The father was active in encouraging aliyah among Iraqi Jews, forging certificates from the British government. His efforts were extremely successful.

Yitzhak studied in cheder, and in the yeshiva he was a gifted student. Following in his brother Yosef’s footsteps, who was older than he, he joined Beitar — and soon after that IZL, despite his young age. Eventually, he left IZL for Lehi. As a youth, his activity was focused on putting up posters in the boulevards and distributing promotional material in mailboxes and public spaces.

One time, British police officers caught him putting up posters, arrested him and put him on trial. His family hired a lawyer, who adopted a strategy of mental incapacity: he argued that Yitzhak suffered from brain damage and did not understand the material he was disseminating. He called the dean of the yeshiva to testify to this “fact.” In addition, before the trial began, they gave Yitzhak a shirt and short pants that made him seem younger than he was. The strategy worked and Yitzhak was acquitted.

It is worth noting that his trial occurred on the same day that Feinstein and Barzani were condemned to death (they would commit suicide with a grenade the night before they were to be brought out to be hanged). The CID was not happy with the verdict. They lay in wait outside the courthouse, and as soon as he was released, they re-arrested him and sent him to administrative detention in Latrun, where he sat for three years. Afterwards, he was transferred to Atlit, to be released only after the State was established and the British left in May 1948.

After this, Yitzhak joined the war effort alongside his Lehi comrades, fighting on the Tel Aviv-Jaffa border against Arab rioters. Then they enlisted in the IDF.

In 1956, he married Leah Shahino, and they had three children and a granddaughter.

Yitzhak passed away on September 16,1985, the first day of Rosh Hashana, and was buried in Holon.
