In 1935 he and his wife Miryam, an equally ardent Zionist, decided to make Aliya.
Miryam was born in Budapest 1902. Her ambition was to study medicine, but due to the ‘Numerus Clausus’ preventing Jews studying at Universities, she had to set aside her plans. She instructed young women in the ‘Kadima’ movement, and eventually joined Beitar, lecturing at Jewish women’s circles. She married Yitzchak1927 and they had a daughter. They made aliya and settled in Haifa; Yitzhak established and managed an Ice factory. He continued Zionist and civic work and was elected member of Hadar-Hacarmel Local Council. He helped establish the Hungarian Immigrants’ Association and ‘Maccabi’ Veterans’ Association. Early 1940s he joined Lehi via Zvi Frunin, a Lehi’s commander wanted by the British CID. Yitzchak and Miryam were entirely identified with Lehi’s cause, assisting in every way they could – among the most dedicated people with Lehi, active in the Haifa region during the war waged by the undergrounds against the British occupier. Their house served members for clandestine meetings. Yitzchak was an ardent nationalist. He helped out members of Etzel and Hagana when needed. Following the assassination of Bernadotte, Yitzchak was arrested by the Israeli Authorities and imprisoned three weeks. He passed away on June 30,1992, aged 94.
