Jacob HaGozer

Rabbi Jacob HaGozer was a prominent German Rabbi and mohel who lived during the early 13th century. As the nephew of Rabbi Ephraim of Bonn, he came from a notable family of Jewish scholars. Rabbi HaGozer made significant contributions to the field of Judaism, particularly in the area of brit milah, or circumcision. He authored a comprehensive work on the laws governing this important ritual, demonstrating his expertise and dedication to the subject.

Rabbi HaGozer's work on brit milah was later published in 1892, alongside a similar work by his son Gershom, under the title Zikhron Berit LaRishonim. This publication highlights the significance of their contributions to Jewish tradition and practice. Notably, Rabbi HaGozer's son Gershom is credited by the Encyclopedia Talmudit as the original source of the Jewish custom of refusing a convert three times before accepting him, a practice that has endured in Jewish communities to this day. Through their writings, Rabbi HaGozer and his son Gershom have left a lasting impact on Jewish law and custom.
