Third Sochatchover Rebbe

Known as the Chasdei Dovid after his halachic work of that name, Rabbi Dovid Bornsztain was the third Sochatchover Rebbe and successor to his father, Rabbi Shmuel Bornsztain. He combined leadership of the Sochatchover Chasidic court with communal rabbinic roles and the establishment of yeshivas patterned on the Sochatchover derech ha‑limud. His responsa and teachings in Choshen Mishpat and other areas of halacha circulated among Polish rabbanim and later formed the basis of the sefer Chasdei Dovid.
