This biographical memoir examines the scholarly career and intellectual contributions of Abraham S. Halkin (1903-1990), Professor of Hebrew at City College and Professor of Jewish Literature and Institutions at the Jewish Theological Seminary. The study employs personal recollections and analysis of Halkin's published works to assess his impact on medieval Jewish studies. Halkin's scholarship focused primarily on Judeo-Arabic texts and Hebrew culture in the medieval Arabic-speaking world, with his methodology rooted in meticulous textual scholarship rather than synthetic analysis. His major contributions included critical editions of Maimonides' Epistle to Yemen (1952), Ibn Aqnin's commentary on The Song of Songs (1964), and Moses Ibn Ezra's treatise on poetry and poetics (1975). The analysis reveals Halkin as embodying what he termed "intellectual responsibility," characterized by exacting standards, comprehensive knowledge, and unwavering commitment to scholarly accuracy. The memoir suggests that Halkin maintained a productive tension between modern intellectual sensibilities and traditional Jewish devotion, hoping that rigorous preservation of textual knowledge would facilitate future synthesis. His approach exemplified the scholarly tradition where Jewish history remained fundamentally the history of texts and intellectual life, representing a generation of orientalist-trained scholars who bridged classical Jewish learning with modern academic methodology.
