This forum examines underrated Jewish thinkers of the 20th century, addressing the question of which influential figures may have been overlooked or undervalued in their time. The article employs a collaborative methodology, inviting various scholars to nominate and analyze individual thinkers who warrant greater recognition. Contributors examine eight figures: Isaiah Berlin (analyzed for his anti-fundamentalist philosophy and dyadic approach to Jewish identity), Hermann Cohen (recognized as foundational to 20th-century Jewish thought through his Neo-Kantian methodology), Amos Funkenstein (noted for his counter-historical approach to Jewish scholarship), Louis Jacobs (examined as a systematic theologian addressing revelation and halakhic authority), Aharon Kotler (credited with transforming postwar Orthodox Judaism through kollel development and institutional changes), Zalman Schachter-Shalomi (recognized for founding the Jewish Renewal movement), Menachem Mendel Schneerson (analyzed for his global outreach strategy), and Steven Schwarzschild (noted for synthesizing liberal ethics with halakhic commitment). The forum concludes with a collective examination of pioneers in Jewish women's and gender studies. The findings reveal diverse contributions spanning philosophy, theology, institutional leadership, and academic scholarship. The study concludes that historical assessments of intellectual influence often reflect contemporary biases and that many significant contributors to Jewish thought remain inadequately recognized, suggesting the need for ongoing reevaluation of the canonical understanding of 20th-century Jewish intellectual history.
