Avrohom Bornsztain
Polish rabbi (1838-1910)
Avrohom Bornsztain (14 October 1838 – 20 February 1910), also spelled Avraham Borenstein or Bernstein, was a leading posek in late-nineteenth-century Europe and founder and first Rebbe of the Sochatchover Hasidic dynasty. He is known as the Avnei Nezer ("Stones of the Crown") after the title of his posthumously published set of Torah responsa, which is widely acknowledged as a halakhic classic. His only son, Shmuel, author of Shem Mishmuel, succeeded him as Rebbe.
Early life
Born in Będzin, Poland on 14 October 1838, Bornsztain was a descendant of the Rema and the Shach. He was the first child of Dobrish (or Doba/Dobela) Erlich, and Rabbi Zev Nachum Bornsztain. Zev Nachum served as Rabbi of Olkusz from 1849 to 1855 and Rabbi of Biała Podlaska from 1855 till his death in 1885. Zev Nachum was the author of Agudat Eizov, and a Hasid of the Kotzker Rebbe. The latter opined that Zev Nachum merited such a son due to his immersion in Torah study on Purim, a time when most people are busy carrying out the many mitzvot of the day.
In his youth, Bornsztain was recognized as an outstanding student with a phenomenal memory. Under the tutelage of his father, who taught him the ways of pilpul, he began writing his own chidushim (new Torah thoughts) at the age of 10.
