Moritz Steinschneider (March 30, 1816, Prostějov, Moravia, Austria – January 24, 1907, Berlin) was a Bohemian bibliographer and Orientalist. He received his early instruction in Hebrew from his father, Jacob Steinschneider (b. 1782; d. March, 1856), who was not only an expert Talmudist, but was also well versed in secular science. The house of the elder Steinschneider was the rendezvous of a few progressive Hebraists, among who was his brother-in-law, the physician and writer Gideon Brecher.
Steinschneider means "stonecutter", or more literally, stone tailor. This likely identifies the profession of gem cutter.
At the age of six Steinschneider was sent to the public school, which was unheard-of at that time for a Jewish child; and at the age of thirteen he became the pupil of Rabbi Nahum Trebitsch, whom he followed to Mikulov, Moravia in 1832. The following year, in order to continue his Talmudic studies, he went to Prague, where he remained until 1836, attending simultaneously the lectures at the Normal School.
In 1836 Steinschneider went to Vienna to continue his studies, and, on the advice of his friend Leopold Dukes, he devoted himself especially to Oriental and Neo-Hebrew literatures, and most particularly to bibliography, which would become his principal focus. His countryman Abraham Benisch and Moravian Albert Löwy also were studying there at the time. In Lowry's room in 1838 they inaugurated among intimate (and lifelong) friends, a proto-Zionist society called "Die Einheit". The society's objective was to promote the welfare of the Jewish people, and in order to realize this objective, they advocated the civilization of Palestine by Austrian Jews. Their objective however, had to be kept secret for fear it would be put down by the government; England became regarded as the country likely to welcome the new movement. In 1841 Lowy was sent to London as an emissary of the Students' Jewish National Society; Benisch also arrived in England the same year. Somewhat abandoned, Steinschneider would later withdrew from the society completely in 1842, viewing the scheme as impractical compared to his studies.
As a Jew on the continent, Steinschneider was prevented from entering the Oriental Academy; and for the same reason he was unable even to obtain permission to make extracts from the Hebrew books and manuscripts in the Imperial Library, Vienna. In spite of these drawbacks he continued his studies in Arabic, Syriac, and Hebrew with Professor Kaerle at the Catholic Theological Faculty of the university. He had at this juncture the intention of adopting the rabbinical career. In Vienna, as formerly in Prague, he earned a livelihood by giving lessons, teaching Italian among other subjects.
University career 
For political reasons he was compelled to leave Vienna and decided to go to Berlin; but, being unable to obtain the necessary passport, he remained in Leipzig. At the university there he continued the study of Arabic under Professor Fleischer. At this time he began the translation of the Qur'an into Hebrew and collaborated with Franz Delitzsch in editing Aaron ben Elijah's 'Etz Chayyim (Leipzig, 1841); but the rules of the Austrian censorship did not permit the publication of his name as coeditor. While in Leipzig he contributed a number of articles on Jewish and Arabic literature to Pierer's Universal Encyklopädie.
Having at length secured the necessary passport, Steinschneider in 1839 proceeded to Berlin, where he attended the university lectures of Franz Bopp on comparative philology and the history of Oriental literatures. At the same time he made the acquaintance of Leopold Zunz and Abraham Geiger. In 1842 he returned to Prague, and in 1845 he followed Michael Sachs to Berlin; but the Orthodox tendencies of the latter caused Steinschneider to abandon definitely his intention of becoming a rabbi. At this time he was employed as a reporter of the National-Zeitung at the sessions of the National Assembly in Frankfurt am Main and as correspondent of the Prager Zeitung. In 1844, together with David Cassel, he drafted the Plan der Real-Encyclopädie des Judenthums, a prospectus of which work was published in the Literaturblatt des Orients; but the project was not carried through by Steinscheider.
On March 17, 1848, Steinschneider, after many difficulties, succeeded in becoming a Prussian citizen. The same year he was charged with the preparation of the catalogue of the Hebrew books in the Bodleian Library, Oxford (Catalogus Librorum Hebræorum in Bibliotheca Bodleiana, Berlin, 1852–60), a work which was to occupy him thirteen years, in the course of which he spent four summers in Oxford.
In 1850 he received from the University of Leipzig the degree of Ph.D. In 1859 he was appointed lecturer at the Veitel-Heine Ephraim'sche Lehranstalt in Berlin, where his lectures were attended by both Jewish and Christian students. From 1860 to 1869 he served as representative of the Jewish community at the administration, before the tribunals of the city, of the oath More judaico, never omitting the opportunity to protest against this remnant of medieval prejudice. From 1869 to 1890 he was director of the Jüdische Mädchen-Schule (school for girls of the Jewish community), and in 1869 he was appointed assistant ("Hilfsarbeiter") in the Royal Library, Berlin. From 1859 to 1882 he edited the periodical Hebräische Bibliographie. In 1872 and 1876 he refused calls to the Hochschule für die Wissenschaft des Judenthums in Berlin and the Landesrabbinerschule in Budapest, respectively, holding that the proper institutions for the cultivation of Jewish science were not the Jewish theological seminaries, but the universities.
His field of activity 
He chose fields far removed from that of theology proper, e.g., mathematics, philology, natural history, and medicine, to display the part which the Jews had taken in the general history of civilization (Kulturgeschichte). While Zunz had laid the foundations of Jewish science, Steinschneider completed many essential parts of the structure. He was the first to give a systematic survey of Jewish literature down to the end of the eighteenth century, and to publish catalogues of the Hebrew books and manuscripts which are found in the public libraries of Europe. The Bodleian catalogue laid the foundation of his reputation as the greatest Jewish bibliographer. This and the catalogues of the libraries of Leiden, Munich, Hamburg, and Berlin, as well as the twenty-one volumes of his Hebräische Bibliographie, form a mine of information of Jewish history and literature.
One of his most important original works is Die Hebräischen Übersetzungen des Mittelalters und die Juden als Dolmetscher: Ein Beitrag zur Literaturgeschichte des Mittelalters; meistenteils nach Handschriftlichen Quellen, Berlin, 1893, planned in 1849. While writing on Jewish literature for Ersch and Gruber's Allgemeine Encyklopädie der Wissenschaften und Künste (1844–47), he became conscious of the lack of sources on the influence of foreign works on Jewish literature. He determined to supplement the monographs of Huet, Jourdain, Wüstenfeld, and Johann Georg Wenrich on the history of translations by one having the Neo-Hebrew literature as its subject. In 1880 the Institut de France offered a prize for a complete bibliography of the Hebrew translations of the Middle Ages; Steinschneider won it with two monographs written in French in 1884 and 1886. His Übersetzungen is an enlarged translation into German of these.
Steinschneider wrote with equal facility in German, Latin, French, Italian, and Hebrew; his style was not popular, intended only "for readers who know something, and who wish to increase their knowledge"; but, curiously enough, he did not hesitate to write, together with Horwitz, a little reader for school-children, Imre Binah (1846), and other elementary school-books for the Sassoon School of the Beni-Israel at Bombay. In 1839 he wrote Eine Uebersicht der Wissenschaften und Künste Welche in Stunden der Liebe Nicht Uebersehen Sind for Saphir's Pester Tageblatt, and in 1846 Manna, a volume of poems, adaptations of Hebrew poetry, which he dedicated to his fiancée, Augusta Auerbach, whom he married in 1848.
