R. Zevi Benjami b. Abraham Auerbach (Hirsch; 1808–1872), a rabbi and rabbinical scholar. He belonged to the first generation of German rabbis with a university education. R. Zevi Benjamin's first rabbinate was Darmstadt (1831–57), where he preached in High German; selections of his sermons were published in 1834 and 1837. He resigned on account of his disagreement with leaders of the congregation, who wished to introduce Reform, and settled in Frankfort, where he devoted his time to research and writing. In 1863 he became rabbi at Halberstadt. In 1868–69 R. Auerbach published the 12th-century halakhic compendium Sefer ha-Eshkol by R. Abraham b. Isaac of Narbonne with a commentary, Nahal Eshkol (repr. 1962). In 1909 R. Shalom Albeck published an "Open Letter" accusing R. Auerbach of forgery. He maintained that the Old Spanish manuscript on which R. Auerbach said he based his edition did not exist and that R. Auerbach, while in Frankfort, had copied from the Carmoly manuscript, but with alterations and additions of his own. J. Schorr, H. Ehrentreu, D. Hoffmann, and A. Berliner wrote Zidkat ha-Zaddik (1910) in defense of R. Auerbach; Albeck wrote Kofer ha-Eshkol (1910) in reply. Albeck's own edition of the Sefer ha-Eshkol (1910, completed by his son Hanokh, 1935–38) shows wide divergencies from R. Auerbach's edition. The alleged Spanish manuscript has never been found. Among R. Auerbach's other works are Berit Avraham (1880), on the liturgy of circumcision; Mishnat R. Natan (1862, repr. 1962), on R. Nathan Adler's Seder Zera'im (1862, repr. 1962); Torat Emet (1893), a manual of the Jewish religion; and (1861).
