Yosef was born in Nes Ziona on October 14,1931 to his father Baruch and mother Shoshana. He was an only child. When he was young they moved to Kfar-Sava in the Sharon area. Yosef studied at Kfar-Sava elementary school and continued at the Vocational High School.  His parents were well off, with high hopes for their son’s future. However the political atmosphere  pervading Kfar-Sava, from where many Lehi and Etzel fighters emerged, influenced his ideological outlook immensely. He was filled with a strong wish to fight the British  regime and sought to expel them from the country. He began associating with youths who felt as he did, in order to make his way to the underground. When his parents understood their son’s intentions, they were horrified and objected strongly to what he was doing. Yosef rebelled, quit his studies, ran away from home and joined Lehi. He was only 16. At the beginning he took part in the routine activities of his age group in the Sharon region, putting up info-bulletins and distributing information material. But he aspired to participate in combat operations against the British. He was transferred – as per his request –  to Lehi’s fighting division and participated in mine-laying operations on roads . He was especially active within the Sharon region. His friends found him a friendly, generous and loyal person, who shared with them even  his single slice of bread. After the declaration of the establishment of the State and establishment of the IDF, Yosef enlisted with his underground comrades and was placed in the 82^nd Battalion’s 8^th Brigade. He participated in all its battles: liberation of Ben-Shemen, Lod and Ramla, and the liberation of Beer-Sheba and the Negev. After all these battles armistice accords were signed and the victory crowned Battalion returned to its Tel-Litvinsky base (today’s Tel-Hashomer). As they were entering the base, literally at its gate, Yosef was hit and  killed, probably by a stray bullet. It happened on August 4,1949. Yosef was brought to rest at the Kfar-Sava cemetery’s Defenders’ Section.
