Abraham Abele Gombiner

Rabbi Abraham Gombiner (Magen Avraham) was a Polish rabbi and legal authority whose rulings have had a decisive impact on Ashkenazi practice. His extreme humility prevented his great Torah learning from gaining him wider recognition, and only when Shabbetai HaKohen (better known as the Shach) visited his town and revealed his greatness did Rabbi Gombiner assume a more senior rabbinic position. His great work, Magen Avraham, on the first section of the Shulchan Arukh, was published posthumously because he lacked the means to publish it during his lifetime.
