September 5, 2026

AI Summary

5 min read

The historian Rabbi Dr. Yitzchak Alfasi, who died this past week in Tel Aviv at a very old age, wrote over ninety books on Jewish history, most of them about the Hasidic movement. He was a Gerrer chassid, a leader in the religious Zionist Mizrachi movement, and a rabbi of a shul—and he did all his research with a pen and paper, never using a typewriter or computer. When he was in his twenties, David Ben-Gurion wrote to him. His critics on the right accused him of retroactively making early Hasidic leaders into Zionists; his critics on the left accused him of being too close to his subjects to be objective. He did not seem to care. Everyone uses his work anyway. This episode uses Alfasi’s life and legacy as a lens to examine the three stages of Hasidic historiography—the writing of the history of the Hasidic movement—and what each stage contributed.

Show Notes

One of the most prolific researchers and writers of Chassidic history, Yitzchak Alfasi amassed an enourmous amount of valuable historic material related to the Chassidic movement, that without his prodigious efforts would have been lost to posterity. Among many others, his invaluable three volume Encyclopedia of Chassidic Personalities is one of the most impressive works of chassidic history ever compiled. When taking a broader view of chassidic historiography, Alfasi fits right in the middle of the dynamic field of researching chassidic history. With its roots in the prewar research of eminent historians such as Shimon Dubnow, and continuing today with new methodologies and sources enriching our knowledge of the chassidic movement, the field of chassidic history research is better than it has ever been before.
