Wilhelm Bacher (; , Benjamin Ze'ev Bacher; 12 January 1850 – 25 December 1913) was a Jewish Hungarian scholar, rabbi, Orientalist and linguist, born in Liptó-Szent-Miklós, Hungary (today Liptovský Mikuláš, Slovakia) to the Hebrew writer Simon Bacher. Wilhelm was himself a prolific writer, authoring or co-authoring approximately 750 works. He was a contributor to many encyclopedias, and was a major contributor to the landmark Jewish Encyclopedia throughout all its 12 volumes . Although almost all of Bacher's works were written in German or Hungarian, at the urging of Hayyim Nahman Bialik many were subsequently translated into Hebrew by Alexander Siskind Rabinovitz. Education Wilhelm attended the Hebrew schools in Szucsány and in his native town, and passed through the higher classes of the Evangelical Lyceum at Presburg from 1863 to 1867, at the same time diligently prosecuting Talmudic studies. In 1867, he began the study of philosophy and of Oriental languages—the latter under Ármin Vámbéry—at the University of Budapest, and also attended the lectures on the Talmud given by Samuel Löb Brill. In 1868, he went to Breslau, where he continued the study of philosophy and philology at the University, and that of theology at the Jewish Theological Seminary of Breslau. He graduated at the University of Leipsic in 1870. His graduation thesis, Nizâmî's Leben und Werke, und der Zweite Theil des Nizâmî'schen Alexanderbuches, appeared in 1871, and was translated into English in 1873 by S. Robinson. This was afterward incorporated in the collection entitled Persian Poetry for English Readers. In 1876, Bacher graduated as rabbi, and shortly afterward was appointed to the rabbinate in Szeged, which had become vacant in consequence of the death of Leopold Löw. Official positions On 1 July, 1877, together with Moses Bloch and David Kaufmann, he was appointed by the Hungarian government to the professorship of the newly created Budapest University of Jewish Studies. Bacher delivered the inaugural address in the name of the faculty at the opening of the institution on 4 October, 1877, and remained as teacher of the Biblical sciences, of Jewish history, and of various other branches at that institution. Bacher was for a time in 1878 field-chaplain in the Austro-Hungarian army, being delegated to the headquarters of the army of occupation in Bosnia. The congregation of Pest, Hungary appointed Bacher director of the Talmud-Torah School in 1885. In 1884, Bacher and Joseph Bánóczi founded the Judæo-Hungarian review, the Magyar Zsidó
