Rosin was the author of: •
"Abschiedswort: Berichte über die Jüdische Religionsschule," Berlin, 1866; •
"Ein Compendium der Jüdischen Gesetzeskunde aus dem 14. Jahrhundert," Breslau, 1871 (on the
"Sefer ha-Ḥinnuk"); •
"Ethik des Maimonides," ib. 1876; •
"Meïr ben Samuel als Schrifterklärer," ib. 1880; •
"Reime und Gedichte des Abraham ibn Esra," in 5 parts, ib. 1885-94 (Ibn Ezra's poems with vocalized text and German transl. in rime). Rosin is most famous for his comprehensive publication of Rashbam's (Rabbi Samuel ben Meir, the grandson of Rashi) commentary on the Pentateuch. He was responsible for making this unique commentary available to the public. He thoroughly analyzed this commentary, citing available manuscripts. Rashbam's commentary is famous for its plain meaning explanations of the Chumash (Pentateuch). This plain meaning explanation of the Chumash is termed peshat in Hebrew. Without Rosin's work, Rashbam's commentary may likely never have been known or published, as all manuscripts of his work were later destroyed during wartime. He edited Michael Sachs'
sermons (2 vols., Berlin, 1867), and he published
Rabbi Samuel ben Meïr's
commentary on the
Pentateuch, with a
Hebrew introduction and Hebrew language analysis, Breslau, 1881. He also published his Rashbam analysis in the German language. An
essay of Rosin's on the philosophy of
Abraham ibn Ezra was edited after his death by his devoted pupil
David Kaufmann and published in the "
Monatsschrift" (vols. xlii.-xliii.), to which
magazine Rosin occasionally contributed. Rosin did his literary work with an exemplary accuracy of detail and in perfect sympathy with his subject. To his numerous disciples he was a kind friend and adviser. In his religious attitude he was strictly conservative, a true disciple of Michael Sachs (whose admirer he was); and he was at the same time broad-minded and tolerant of the opinions of others. His only son,
Heinrich Rosin, was a professor of
medicine at the
University of Berlin. Another relative, a nephew,
Heinrich Rosin, was a professor in the law department of the
University of Freiburg. == References ==
