|Occupation||Rabbi and historian|
Moritz (Moshe) Güdemann attended the Jewish school in Hildesheim, and thereafter went to a Catholic Gymnasium. He was educated at the University of Breslau (Ph.D. 1858), and took his rabbinical diploma (1862) at the newly founded the Jewish Theological Seminary there. In the latter year he was called to the rabbinate of Magdeburg; in 1866 he went to Vienna as preacher, where he became rabbi in 1868, and chief rabbi in 1892.
He married his first wife, Fanny Spiegel, in 1863. After her death he married Ida Sachs, with whom he had four children.
Gudemann protested the proposal to strike from the prayer-book all passages referring to the return of the Jews to the Holy Land (compare his sermon "Jerusalem, die Apfer und die Orgel," 1871). He threatened to resign over this issue. There are conflicting versions of his support for Theodor Herzl's Zionist schemes. Herzl wrote that Gudemann believed his book Der Judenstaat could "work wonders," but Gudemann later denied this and dissociated himself from any nationalist interpretation of the Bible and its promise of Jewish redemption. 
Güdemann wrote on history of Jewish education and culture, and was associated with the Wissenschaft des Judentums movement. In addition to dozens of articles, he published the following monographs:
- "Die Geschichte der Juden in Magdeburg," 1865
- "Die Neugestaltung des Rabbinenwesens," 1866
- "Sechs Predegten," 1867
- "Jüdisches im Christenthum des Reformationszeitalters," 1870
- "Jüdisches Unterrichtswesen Während der Spanisch-Arabischen Periode," 1873
- "Religionsgeschichtliche Studien," 1876
- "Geschichte des Erziehungswesens und der Kultur der Abendländischen Juden," 3 vols., 1880–88
- "Nächstenliebe," 1890
- "Quellenschriften zur Gesch. des Unterrichts und der Erziehung bei den Deutschen Juden," 1894
- "Das Judenthum in Seinen Grundzügen und nach Seinen Geschichtlichen Grundlagen Dargestellt," 1902
