David Cassel’s doctoral thesis on biblical headings, published in 1840, initiated a prolific career in philology and theology that spanned over five decades. A product of the vibrant intellectual climate of Głogów, he spent his adult life in Berlin, where he emerged as a central figure in the institutional development of Jewish scholarship during the nineteenth century.
Academic Formation and Early Struggles
Born in 1818, Cassel pursued his studies at Humboldt-Universität zu Berlin. He attended lectures by prominent scholars including the orientalist Julius Heinrich Petermann and the philosopher Friedrich Adolf Trendelenburg. During his university years, he experienced significant financial hardship, which led him to provide private instruction to sustain himself. This formative period motivated him to help establish the Hülfs-Verein für Jüdische Studierende, an organization created to support indigent students in Berlin.

Although Cassel received a rabbinical diploma in 1843 from Jacob Joseph Oettinger and Zecharias Frankel, he did not pursue a career in the rabbinate. Instead, he dedicated himself to education, serving as the principal of the Dina-Nauen-Stift from 1846 until 1879. He also held various teaching roles at the Congregational School for Jewish Girls, the Jewish school for boys, and the Jewish Normal School. When the Hochschule für die Wissenschaft des Judentums was founded in 1872, he was appointed as one of its docents.
Scholarly Contributions and Editorial Work
Cassel maintained an extensive output of books, essays, and critical editions. His work included a Hebrew-German dictionary and historical textbooks that were translated into multiple languages. He also provided introductions and critical notes for works by authors such as Judah ha-Levi, Azariah dei Rossi, and Isaac Israeli. Beyond these projects, he authored entries on Jewish literature for Brockhaus’ Konversations-Lexikon and contributed to various academic journals, firmly establishing his influence in the fields of history and philology.
