The Jewish Encyclopedia
The Jewish Encyclopedia: A Descriptive Record of the History, Religion, Literature, and Customs of the Jewish People from the Earliest Times to the Present Day is an English-language encyclopedia containing over 15,000 articles on the history, culture, and state of Judaism up to the early 20th century. The encyclopedia's managing editor was Isidore Singer and the editorial board was chaired by Isaac K. Funk and Frank H. Vizetelly.
The work's scholarship is still highly regarded. The American Jewish Archives deemed it "the most monumental Jewish scientific work of modern times", and Rabbi Joshua L. Segal said "for events prior to 1900, it is considered to offer a level of scholarship superior to either of the more recent Jewish encyclopedias written in English."
