Yosef was born in 1952, the sixth son of the future Shas' spiritual leader and Israeli Chief Rabbi, Ovadia Yosef [REF].
In 1971, when he was 18 and studying at Yeshivat HaNegev, he collected halakhic rulings from the five volumes of Yavia Omer, the book of his father's responsa, that had been published by then, and published them in the book Yalkut Yosef.
