Rabbi Avraham Yitzchak Weinberger (1805-1885) was Rabbi Tzvi Hirsch Heller-Charif’s son-in-law. When his father-in-law passed away, and the latter’s widow married the Chatam Sofer, he moved to Pressburg where he had an exceptionally close relationship with his step-father-in-law.
In 1832, he served as Av Beit Din in Freistadt, where he learned with Rabbi Chaim Tzvi Manheimer, Av Beit Din Ungvar and Rabbi Meshulem Feish Segal of Tosh. In 1844, he began his forty year term in Kleinwardein. He was friendly with Rabbi Chaim of Sanz and corresponded with him on halachic matters. His printed writings include the Pnei Yitzchak on the Talmud (Munkacs, 1892) and Milel Avraham on the Torah (Munkacs, 1913). To the best of our knowledge, these novellae were never printed.
