This commemorative article presents a comprehensive assessment of H.L. Ginsberg's scholarly contributions to ancient Semitic philology spanning forty-five years of research. The analysis employs a biographical-critical methodology, examining Ginsberg's work across multiple disciplinary domains including Biblical Hebrew, Ugaritic, Aramaic, and Phoenician studies. The article demonstrates Ginsberg's exceptional mastery of diverse linguistic tools, from Biblical Hebrew through Modern Hebrew, and his pioneering role as the acknowledged dean of Ugaritology since its inception. Key findings highlight his foundational contributions to Ugaritic grammar, particularly the Barth-Ginsberg Law concerning thematic vowel vocalization, and his groundbreaking lexicographical discoveries that illuminate both Ugaritic and Biblical texts. The study details his innovative text editions, including the definitive monograph on the Legend of King Keret (1946) and translations in Ancient Near Eastern Texts (1950), which remain authoritative works. Ginsberg's methodological approach combines rigorous philological analysis with deep sensitivity to ancient idiom and poetic style. His contributions to Aramaic and Phoenician dialectology, including identification of local variations in "Official Aramaic" and Standard Phoenician pronominal systems, demonstrate his analytical precision. The article concludes that Ginsberg's scholarship, characterized by meticulous textual emendation based on comprehensive linguistic knowledge, represents one of the most remarkable scholarly accomplishments in contemporary Biblical and ancient Near Eastern studies.
