Yehuda was born 1923 to his parents Dov and Rivka Feder, a family of seven in Zlotniky Poland. The family baked and sold bread. A Zionist household, the mother was active in the Nationalist Women Alliance. Yehuda studied at elementary school mornings and Talmud-Torah afternoons. Aged 11 he joined Beitar. After Bar-Mitzvah he was sent to ‘Stanislav Yeshiva’, excelled in his studies, which enabled his receiving a scholarship, and immigrating with a two-year entry permit. World War II broke out, in which his entire family perished except sister Tova, who arrived in Israel later. Parallel to studies at the ‘New-Yeshuv Yeshiva’ Tel-Aviv, he joined ‘Brit- Hachashmonaim’. Yehuda joined Etzel, undergoing weapons training, various courses. After the split he joined Yair. In Lehi he was involved in instruction, recruiting new members, and distributing info-material. He participated in the attack on the British Military Camp in Holon, for confiscating weapons. For a while he liaised between Gera (Nathan Yelin-Mor) and the Lehi printing house in the orchards of Magdiel bringing Gera’s notes to print. To avoid searches and scrutinizing Jewish eyes, he adopted the look of a ‘Hashomer-Hatsa’ir’ orchard worker (blue shirt, short trousers) carrying a double bottomed lunch-box, where the incriminating documents were hidden. February 1946 he was arrested and sentenced to six years for possessing a weapon. After two years he escaped Jerusalem Central Prison through a tunnel, immediately resuming activities within the Lehi Brigade in besieged Jerusalem. He participated as head of the Religious Group, in the battles of Deir-Yassin, Shuefat, Ein-Karem, conquest of Notre Dame, the Fast Hotel, and in the attempt to break into the Old City. After Lehi’s dismantlement, he joined the Israeli army. After release he married Rachel Dichter, and worked for the Ministry of Health forty years, retiring 1991. Between 1986-94 he served as chairman of the Likud branch Jerusalem. As pensioner he established a Jerusalem synagogue for the fallen soldiers of Etzel and Lehi, where memorial services are held in their commemoration. In April 2001 he was awarded the “Jerusalem Notable Citizen” Award.
