Yakov Azriel was born in New York, in 1950, as Gerald Rosenkrantz. After receiving his B.A. in English literature, summa cum laude, at Brooklyn College, in 1971, he moved to Israel, where he changed his name to Yakov Azriel. He studied at the Mercaz HaRav Kook Yeshiva, in Jerusalem, and the Har-Etzion Yeshiva, in Alon-Shvut, Israel, and later completed an M.A., with distinction, and a doctorate in Judaica, concentrating on the stories of Rabbi Nachman of Braslav.
