R. Moses Samuel Glasner (1856–1924), rabbi and early leader of the Mizrachi movement in Hungary and Transylvania. Glasner, a great-grandson of R. Moshe Sofer, was born in Pressburg. From 1878 until 1923, when he settled in Erez Israel, he was the rabbi of Klausenburg. He was one of the two Orthodox rabbis in Hungary (the other being Moses Aryeh Roth) who joined the Zionist movement and Mizrachi, and at the founding convention of Mizrachi (Pressburg, 1904) he spoke out against the Orthodox Hungarian rabbis for their attacks upon Zionism and the Mizrachi. He propagated the Zionist idea in speeches and writings among Orthodox circles. He also published several halakhic works (Or Bahir, 1908; Halakhah le-Moshe, 1912; Dor Revi'i, 1921) and a work on the aggadah, Shevivei Esh (1903). In Jerusalem, he took part in the educational and cultural activities of Mizrachi and was especially close to Rabbi A. I. Kook.
