GUGGENHEIM-GRUENBERG, FLORENCE (1898–1989), pharmacist and historian, born in Berne, Switzerland. During the 1930s and 1940s she was active in Swiss Jewish national and international organizations, and from 1950 was president of the Juedische Vereinigung in Zurich. She was the editor of Beitraege zur Geschichte und Volkskunde der Juden in der Schweiz, a series devoted to the history and folklore of the Jews in Switzerland. She edited the typescript of Augusta Weldler-Steinberg and added chapters on the history of the communities of Lengnau and *Endingen in the two-volume Geschichte der Juden in der Schweiz (1966/1970), a history of the Jews in Switzerland from the 16th century to the period after emancipation. She was one of the first researchers of western Yiddish after 1945, providing ample oral documentation of a then nearly extinct dialect, and she fought for women's rights in Switzerland.
