Isidore Israel Goldblum (Israel Isser Goldblum; 26 June 1863 – 2 March 1925), also known by the pen names Peraḥ Zahav and Yafaz, was a Hebrew writer and bibliographer.
Isidore Israel Goldblum was born to a Jewish family in the town of Neishtot Shaki, where he received a traditional religious education. He studied at the yeshivot of Eyshishok, Volozhin, and Pressburg, and later studied Jewish law under Dr. Ze'ev Feilchenfeld in Poyzn.[1]
He devoted himself to the study and publication of Hebrew manuscripts in Berlin, Paris, London, Oxford, and Rome, publishing his research mainly in the periodical Ha-Maggid. In 1891 he wrote Vie et Œuvres de rabbi Elia Bahur le Grammairien, a short biography of Elye Bokher.[2] That same year he published Ma'amar Bikkoret Sefarim, and released his Mi-Ginzei Yisrael be-Paris in 1894. He corresponded with the leading Jewish scholars of his time and published a collection of these letters (Kevutzat Mikhtavim, 1895).[3]
