The Jewish family has been the subject of much admiration and analysis, criticism and myth-making, not just but especially in modern times. As a field of inquiry, its place is at the intersection – or in the shadow – of the great topics in Jewish Studies and its contributing disciplines. Among them are the modernization and privatization of Judaism and Jewish life; integration and distinctiveness of Jews as individuals and as a group; gender roles and education. These and related questions have been the focus of modern Jewish family research, which took shape as a discipline in the 1910s. This issue of PaRDeS traces the origins of academic Jewish family research and takes stock of its development over a century, with its ruptures that have added to the importance of familial roots and continuities. A special section retrieves the founder of the field, Arthur Czellitzer (1871–1943), his biography and work from oblivion and places him in the context of early 20th-century science and Jewish life. The articles on current questions of Jewish family history reflect the topic’s potential for shedding new light on key questions in Jewish Studies past and present. Their thematic range – from 13th-century Yiddish Arthurian romances via family-based business practices in 19th-century Hungary and Germany, to concepts of Jewish parenthood in Imperial Russia – illustrates the broad interest in Jewish family research as a paradigm for early modern and modern Jewish Studies.

Due to the lack of acceptance of Wissenschaft des Judentums in academia, modern Jewish scholarship in the nineteenth century organized itself along networks of institutions such as rabbinical seminaries, contacts with related disciplines like Oriental Studies, and personal relationships. This last pathway of communication was essential for the cohesion of modern Jewish scholarship. Therefore, my essay portrays the correspondence between David Kaufmann and Leopold Zunz as an example of this channel of communication. By analyzing the exchange of letters and personal encounters between the two scholars, particular attention will be paid to the following questions: How were the letters transmitted until today? What were the main topics of the correspondence between these representatives of two generations of Wissenschaft des Judentums? Which were the positions of Kaufmann and Zunz towards the present and future of modern Jewish scholarship? How did Kaufmann become the first biographer of Zunz?
