R. Simhah Bunim b. Moses Eger(1770–1829), Hungarian talmudist, younger brother of R. Akiva Eger the Younger. R. Eger was also known by the family names of Guens and Schlesinger. After studying under his brother R. Akiva and then continuing his studies in Krotoszyn, he was appointed rabbi of Rogasen and in 1810 of Mattersdorf, where he remained until his death. Some of his novellae are printed in his brother's Hiddushei Rabbi Akiva Eger (1858) which also includes their halakhic correspondence. Eger was also in correspondence with his relative R. Moses Sofer, with R. Mordecai Michael Jaffe, author of Beit Menahem, and with R. Israel Moses b. Aryeh Loeb, author of Rishmei She'elah. His novellae were later published as an appendix to his brother's responsa (2nd part; 1938).
