R. Esriel Hildesheimer (Wikipedia bio) was a founding figure in Modern Orthodoxy. He established what became known as the Hildesheimer Rabbinical Seminary in Berlin, a yeshiva that advocated academic Jewish scholarship within the confines of Orthodox Jewish beliefs. A formidable rabbinic scholar, his Talmudic commentaries were published only approximately twenty years ago with, perhaps surprisingly and perhaps not, a glowing approbation from R. Elazar Schach. HebrewBooks houses the 1969 and 1976 editions of R. Hildesheimer’s responsa: vol. 1 (Orach Chaim/Yoreh Deah) – link, vol. 2 (Choshen Mishpat/Even HaEzer): link.
