Overview

Zikhron Aharon (Hebrew: מכון זכרון אהרן, Makhon Zikhron Aharon) is a Torah publishing institute and press based in Jerusalem, Israel. It was founded in the early 2000s (around 2003) by Rabbi Yonatan Bleyer, a New York resident, initially to print and distribute the works of his grandfather, Rabbi Yonatan Steif.

History

Zikhron Aharon was founded in the early 2000s (around 2003) by Rabbi Yonatan Bleyer, a resident of New York. The primary motivation for establishing the institute was to print and distribute the books of his grandfather, Rabbi Yonatan Steif. Among the initial publications were Sefer Mitzvot Hashem, She'elot u-Teshuvot Mahar'i Steif, and Sefer Chadashim Gam Yeshanim. After its initial focus on Rabbi Steif's works, the institute expanded its publishing activities to include a broader range of Torah literature. It began to publish works by other prominent rabbinic authorities, such as Rabbi Yehonatan Eybeschutz and Rabbi Yaakov Emden (the Yaavetz). A major emphasis was placed on Midrashic literature, and the institute became known for its editions of Mekhilta de-Rashbi, Mekhilta de-Rabbi Yishmael, Seder Olam, Midrash Tanchuma, Pirkei de-Rabbi Eliezer, and many others. Over time, it published more than forty volumes of Midrashim. The institute also engages in the research and publication of manuscripts by leading Rishonim and Acharonim, encourages Torah research, and disseminates Torah publications on Halakhah and Aggadah. It operates a research center for Halakhic literature called Ohel Yonatan u-Vluma, named after Rabbi Yonatan Steif. As of 2019, the institute had published hundreds of books, including nearly all existing Midrashim. Its books are edited with modern notes, references, and commentary, in line with the practices of contemporary Torah publishing institutes. The institute is headquartered in Jerusalem and is headed by Rabbi Yonatan Bleyer. Its distribution website, Orayta Books, serves customers in Israel and internationally.
