MENDL ROZENHOYZ (ROZNHOYZ) (1901-1982)
He was a Soviet Jewish bibliographer, born in Bobruisk, Byelorussia, descended from a highly devout family. He graduated from middle school there, and in 1922 he began working in the Bobruisk municipal Jewish library; in 1924 he moved to Moscow to work for the central Jewish library in Moscow and in other Jewish libraries as well. He wrote bibliographical surveys of published Yiddish books for: Emes (Truth) in Moscow; Oktyabr (October) and Shtern (Star) in Minsk; and Sovetish (Soviet) in Moscow; among others. With the start of WWII, he went off to the front, and after demobilization he returned to work for the library of Emes publishers. He experienced much in connection with the tragedy of the Yiddish book in the Soviet Union. Particularly difficult was the elimination of Yiddish libraries at Emes publishers and Eynikeyt (Unity). He later published articles and notices on Soviet Yiddish bibliographers who had died or were murdered in the ghettos or at the front, mainly in Sovetish heymland (Soviet homeland) in Moscow, for which he was in charge of the bibliographic section. He was overjoyed when the journal invited him to be in charge of putting together a library for the journal. He effectively saved many books from destruction.
