LEVEEN, JACOB (1891–1980), librarian and author. Born in Jerusalem, Leveen studied in England and worked for many years in the Department of Oriental Books and Manuscripts of the British Museum, from 1953–56 as keeper. He was responsible for part 4 of the Catalogue of Hebrew and Samaritan Manuscripts in the British Museum (1935). His Hebrew Bible in Art (1944, the British Academy's Schweich lectures, 1939) was a pioneer study in this field. Leveen also published a facsimile edition of a unique British Museum manuscript of Zechariah b. Judah Aghmati's digest of commentaries on the three Bava tractates of the Babylonian Talmud (1961). He prepared the second part of a catalog of Hebrew manuscripts in the Cambridge University Library (unpublished).
