Mnachem Risikoff

Mnachem (Mendel) HaKohen Risikoff (1866–1960), was an orthodox rabbi in Russia and the United States, and a prolific author of scholarly works, written in Hebrew. Risikoff used a highly stylized and symbolic pen-name, יאמהדנונחהים, made up of the Hebrew letters of his first name, the Hebrew word for Lord, and the Tetragrammaton, one of Judaism's terms for God. It is not clear whether this pen name was used in conversation, or whether it was used only in his writings.

Risikoff, the son of well-known Rosh yeshiva (Talmudic Academy Dean) Rabbi Zvi Yosef Resnick, was born in Zhetel, later studying in yeshivot, academies, in Volozhin and Vilna, where he received semikhah (rabbinic ordination) at the age of 17 from a number of well-known rabbis: Yosef Shlupfer, from Slonim; Avraham DovBer HaKohen Shapira, from Riga; Shlomo HaKohen, author of Binyan Shlomo, from Vilna; Katriel Nathan, Av Beit Din of Augustów; and Eliyahu Adran, of Grajewo; with other rabbis later adding their ordination as well.

In 1895, after serving as rabbi in a small town in Lithuania, he was appointed rabbi of Kazan. He emigrated to the United States in 1906, following anti-Jewish riots in that area, serving as rabbi in a number of synagogues in Brooklyn, including Ohev Shalom, in Brownsville;Keter Israel; Beth Ha-Knesseth Adath B'Nai Israel, also referred to as Williamsburg's Moore Street Congregation; and finally, Dibre Mnachem, a congregation named after the first book Risikoff published after moving to the United States, located in the area now known as Bedford-Stuyvesant, on one floor of the building where he lived for many years, until his death in 1960.
