Yosef Yitzchok Lerner (רבי יוסף יצחק לרנר) is a Hareidi, American-born, Rabbi in Jerusalem who is known for writing several popular books on Jewish law and custom. He also heads Beis Midrash L'Horaah Toras Shlomo, a Kollel for rabbinic ordination.
Lerner was born to Shmuel Yechiel Lerner a Holocaust survivor from Hungary, in Forest Hills, NY. His mother, Grace Lerner, was born and raised in Newark, New Jersey. At a young age, the family relocated to Chicago, Illinois. As a teenager, he studied in the Telz Yeshiva in Chicago and, later, at the Yeshiva of Rabbi Dovid Soloveitchik in Jerusalem. He also studied at Beth Medrash Govoha in Lakewood, NJ under the tutelage of Rabbi Shneur Kotler.
He married a daughter of the Mohel of Jerusalem, Rabbi Yosef Dovid Weissberg[1] and learned in the Kollel of Shaar Hashamayim Yeshiva under the leadership of the leading posek of his time, Rabbi Shlomo Zalman Auerbach.
He studied Halacha as an apprentice to Rabbi Moshe Halberstam whom he views as his mentor in terms of halachik decisions. He also served as a lecturer for Aish HaTorah's Halacha program.
After leaving his position at Aish HaTorah, Lerner started a Kollel in which he teaches and prepares English-speaking students for rabbinic ordination. The honorary president of his Kollel was originally Rabbi Lerner's mentor, Rabbi Moshe Halberstam, who signed the rabbinic ordination. After Rabbi Halberstam's death in 2006, the mantel of the Kollel's honorary leadership was passed to Rabbi Moshe Sternbuch who co-signed the Rabbinic ordination with Lerner, until other circumstances in his life caused him to pull back from involvement in other projects in 2014. Since then Rabbi Avraham Yitzchok Ulman of the Badatz Eidah Hachareides has taken over honorary leadership and co-sign the Rabbinic ordination.
A letter of Rav Sholomo Zalman Aerubach in Rabbi Lerner's book played a limited role in the affair surrounding the controversy of the works of Natan Slifkin because in one of his works, Lerner published a letter penned by Rabbi Shlomo Zalman Auerbach which discusses the correlation between rabbinic teachings and contemporary scientific knowledge.[6][7][8]
