Sochatchov (Yiddish: סאכאטשאוו) is a Hasidic dynasty originating from the town of Sochaczew, Poland, where it was founded by Avrohom Bornsztain (1838–1910).
[1] After the Kotzker Rebbe's death, Bornsztain became a Hasid of his uncle, Yitzchak Meir Alter, the Chidushei HaRim of Ger.
His voluminous responsa on every section of Shulchan Aruch were published posthumously in seven volumes under the title Avnei Nezer ("Stones of the Crown").
[3] The third Sochatchover Rebbe, Dovid Bornsztain (1876–1942), eldest son of Shmuel, grew up near his grandfather, the Avnei Nezer, who was his primary teacher.
[6] He was an active member of Agudath Israel of America and the Moetzes Gedolei HaTorah[4] and became known as one of the generation's leading Rebbes.
[7] When the deportations began, Dovid hid in a shop on 67 Genesha Street, where he died of heart failure on 17 November 1942.
These pages were later published as Chasdei Dovid together with the ninth volume of Shem Mishmuel, his father's work, which deals with the Haggadah.
[10] The Avnei Nezer and his son, the Shem Mishmuel, produced a body of teachings that are widely acknowledged as halakhic and homiletic Torah classics.
[13][14] The homiletic essays of the Shem Mishmuel have earned a following in both the Hasidic and non-Hasidic world, and are quoted in many Torah shiurim and books.
