Rav Chaim Ozer Grodzinski’s Letters Reveal a Leader at the Center of Jewish History

The second volume of Rabbi David Kamenetsky’s Hebrew-language biography of Rav Chaim Ozer Grodzinski covers the years 1910 to 1930—a period when Grodzinski was arguably the most influential Jewish leader in Eastern Europe.

Grodzinski was perhaps the most prolific letter writer in Jewish history. He corresponded on every conceivable topic—communal politics, yeshiva funding, religious disputes, personal tragedies—and Kamenetsky has spent years locating, organizing, and contextualizing these letters. The book also includes letters written to Grodzinski by other major figures of the time: Yaakov Rosenheim of Agudat Yisrael, the Lubavitcher Rebbe (Rabbi Shalom Dovber Schneersohn), Rabbi Avraham Yitzchak Kook, and many others. The volume is packed with photocopies of original documents—letters, newspaper articles, conference protocols, public proclamations—numbering in the hundreds.

The newly published excellent book in Hebrew about the life and times of Rav Chaim Ozer Grodzinski (1863-1940) by Rav David Kamenetsky, entitled Rav Chaim Ozer Grodzinski: Rabban shel Kol Bnei Hagola Volume 2, is a great contribution to our historical understanding both of this great leader and the entire era in which he operated. This second volume covers the years 1910-1930, and - just like the first volume - utilizes the vast repository of Rav Chaim Ozer’s own many letters to tell his story using his own words. This meticulously researched work organizes Rav Chaim Ozer’s and his correspondent’s letters for the first time, allowing the narrative of major events in the Jewish world to be told by the protagonists themselves. Topics include the Katowice conference of Agudas Yisrael in 1912, World War I and its aftermath, the first Knessiah Gedola of Agudas Yisrael in Vienna in 1923, the Vilna Jewish community, the Vaad Hayeshivos & its Dos Vort newspaper, the dispute surrounding the Vilna rabbinate, and many others. This highly recommended book is a vital contribution to our understanding of Jewish history of that era.
