Rabbi Avrohom Yitzchok Kohn (4 January 1914 – 8 December 1996) was a Hasidic rabbi and founder of the Toldos Aharon Hasidim.[1] He was the son-in-law of Rabbi Aharon Roth, and the Toldos Avrohom Yitzchok is named after him.[2]
Kohn was born in Safed to Rabbi Aharon David and his wife Scheindel Bracha.[3] His mother was the granddaughter of Rabbi Avraham Yitzhak Heller, son of Rabbi . As a child, his family moved to Transylvania, Romania. He studied with Rabbi Yisrael Friend of Hunyad, the son of Rabbi and with Rabbi .
