Rabbi Moritz Grünwald (also spelled Greenwald; 1853–1895), born in Uherské Hradiště in the Austrian Empire (now the Czech Republic), was the Chief Rabbi in the cities of Bjelovar, Písek, and Mladá Boleslav, and later served as Chief Rabbi for the Principality of Bulgaria. Additionally, he was a writer and editor who wrote about the history of Jews and on linguistics of Jewish languages. He attended both the University of Vienna and the Leipzig University, attaining degrees in philosophy and theology. In 1881, he was ordained as a rabbi by the Jewish Theological Seminary of Breslau,[2] and appointed Chief Rabbi of Bjelovar in modern-day Croatia. From 1884 and 1893, he served as Chief Rabbi in the cities of Písek and Mladá Boleslav in Bohemia. In Bulgaria, he wrote a guide for Jewish teachers and instructed faculty in the schools in the community, while simultaneously conducting research on the history of Bulgarian Jewry, traveling the land and examining tombstones and archaeological sites. As a Yiddish philologist, he embraced a German identity within Ashkenazi Jewish language. He stated that it should be considered "analogous to other German dialects." Taking interest in Sefaradi Jewry, he also published a monograph of Judezmo in 1882, the first to do so. For over a decade, he was an editor for Das jüdische Centralblatt auch Archiv für die Geschichte der Juden in Böhmen.
