Ephraim Deinard (1846–1930) was one of the greatest Hebrew "bookmen" of all time. He was a bookseller, bibliographer, publicist, polemicist, historian, memoirist, author, editor, and publisher, all rolled into one. Deinard produced some 70 volumes whose subjects range from Jewish history and antiquities (especially of the Crimea, Russia, America, and The Holy Land), to treatises against Hasidism, Christianity, and Communism, parodies, medieval and modern Hebrew literature, Jewish religion, and especially booklore.
