R. Hayyim ben Mordecai Ephraim Fischel Sofer, (1821–1886), Hungarian rabbi was an outstanding pupil of Hatam Sofer in Pressburg and of Meir Eisenstaedter in Ungvar. R. Hayyim was appointed head of the yeshivah at Mattersdorf in 1844. He served as rabbi of Gyomro in 1852, of Sajoszentpeter in 1859, and of Munkacs in 1867. Persecuted by the Hasidim despite his religious extremism, he left Munkacs in 1880 and was appointed the chief rabbi of the Orthodox community in Pest. He was one of the leading extreme Orthodox rabbis in Hungary, a signatory, of "the infamous excommunication" of the maskilim in Michalovce, and a central figure of the Shomerei ha-Dat organization. He demanded that adherents of the Reform movement be excommunicated and that their sons be refused circumcision.

R. Hayyim was also the author of the following works: Peles Hayyim (1854), novellae on the first chapter of Gittin; Sha’arei Hayyim (1869), admonitions against the Reformers; Kol Sofer (2 pts., 1881–82), on the Mishnah; and Sha’arei Hayyim (1892), a commentary on Psalms. Reference Description
