Pesach was born on 3.3.1922 in the town of Zaklików, Poland, to Reisha and Eliezer. His father was a local Beitar commander, and he was raised in a nationalist home where he learned Hebrew. The family made aliyah in 1936 and lived in Tel Aviv. Pesach studied at the Montefiore School, and when he graduated, he went to work in a workshop which repaired electrical engines.
At seventeen, he joined the IZL, and when it split, he followed Yair to Lehi. During the Saison of late 1942, Pesach was captured by the Hagana and kept in a packing factory in a kibbutz. He was interrogated and tortured over a number of days for his activity and the planned assassination, but he gave up nothing. Unfortunately, the attempt on Morton’s life was unsuccessful.
Pesach was turned over to the British and put in administrative detention in Mizra. After Shamir and Giladi escaped in September 1942 and they were transferred to Latrun, and after twenty Lehi men escaped from Latrun by way of a tunnel (a year later), the British decided to deport the detainees to Africa.
Pesach was in the first group to be exiled. They were sent first to Sembel (near Asmara, Eritrea), then to Carthago (Sudan). On 27 January 1945, they were returned to Eritrea, then sent to Gilgil (Kenya) on 12 March 1947.
Throughout this period, Pesach created art with his hands. He took courses at the University of London via correspondence and passed with honors. He also began pursuing an engineering degree at another English school. He also took courses at the camp: Uzi Arnon taught Hebrew (he would later become a linguistics professor at Jerusalem’s Hebrew University), Yitzhak Zellnick taught English, and a Technion graduate taught a mechanical course on the structure of the lathe.
On 15 May 1948, the day the State was established, Pesach was released and sent home, five-and-a-half years after he was first arrested. He enlisted in the IDF, serving throughout the War of Independence.
Afterwards, Pesach opened a workshop for repairing electric engines; later, he opened a factory for manufacturing electric engines and gears in Yahud.
In 1950, he married Doris Weitz. Her family had fled from Germany to China before World War II began, making aliyah a decade layer. They have a son and two daughters, all three of whom served in the IDF.
