Yitzhak Moshe (Itamar) Elbogen was born in Posen.^[1] He was taught by his uncle, Jacob Levy, author of the "Neuhebräisches Wörterbuch", and then attended the gymnasium and the Jewish Theological SeminaryinBreslau.^[2] He earned his doctorate from the Breslau University and was ordained as a rabbi in 1899.

Elbogen served as a lecturer on Biblical exegesis and Jewish history at the Collegio Rabbinico ItalianoinFlorence. In 1902 he became privat-docent at the Lehranstalt für die Wissenschaft des JudentumsinBerlin. He fled Nazi Germany in 1938, and taught at the Jewish Institute of Religion in New York, the Jewish Theological Seminary and Hebrew Union College.

He is the author of Jewish Liturgy: A Comprehensive History. Originally published in German in 1913, this book was updated in a number of subsequent Hebrew editions. The latest Hebrew edition was translated into English by Raymond P. Scheindlin, and published by the Jewish Publication Society in 1993.

This work covers the entire range of Jewish liturgical development, beginning with the early cornerstones of the siddur; through the evolution of the medieval piyyut tradition; to modern prayerbook reform in Germany and the United States. It is the most thorough academic study of the Jewish liturgy ever written.
