Avrohom Yitzchok Kohn

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 Shmuel Heller. As a child, his family moved to Transylvania, Romania. He studied with Rabbi Yisrael Friend of Hunyad, the son of Rabbi Avraham Yehoshua Freynd and with Rabbi Yehuda Segal Rosner. He was a disciple and follower of Rabbi Joel Teitelbaum, the Satmar Rebbe.

Following Roth's death in 1947, many Hasids turned to Kohn as his successor, who became the rabbi of Toldos Aharon. A minority of rebbes chose his brother-in-law, Rabbi Avrohom Chaim Roth, who founded the Shomer Emunim Hasidism.[4] During his leadership, Hasidic institutions were established across Israel and the United States. He wrote the Divrei Emunah in 1967.

He died on 8 December 1996 during Hannukah after nearly 50 years of leadership of his branch of Hasidism.[5] A majority of his followers supported his son, Rabbi David Kohn, as his successor. The rest became followers of David's elder brother, Rabbi Shmuel Yakov Kohn, who established a new court. He is buried at the Mount of Olives Jewish Cemetery.[3]

Rabbi Meir Brandsdorfer was a notable student of his.
