Salomo A. Birnbaum (1891?1989) is the uncontested pioneer in two large closely related research areas, namely historical Jewish linguistics and the palaeography of Hebrew and all Jewish successor languages. This collection of essays provides a cross-section through Birnbaum’s life’s work. Volume I contains articles on Jewish philology and a survey of additional Jewish languages and individual studies. Volume II documents the development of Hebrew palaeography, which began to be established in the period between the 1930s and 1960s.
