{{Short description|12th century German Rabbinic scholar}} '''Eliezer ben Yoel HaLevi of Bonn''' (Hebrew acronym {{Script/Hebrew|ראבי״ה}} '''Ra'avyah'''; 1140–1225<ref group="Note">To be more precise, it is only known that he died after 1220.</ref>) was a Rabbinic scholar in Germany. He had a significant influence on Asher ben Jehiel (the ROSH). As a Rishon, he was prominent amongst the Tosafists of the middle-ages, and was a signatory to the Takkanot Shum. In the course of his long life he wandered from place to place: Bonn, Worms, Würzburg, Mainz, Cologne, Regensburg, and throughout France and Lombardy.<ref>1972 Encyclopedia Judaica: "Eliezer ben Joel HaLevi of Bonn"</ref>
His maternal grandfather was Eliezer ben Nathan (Ra'avan). Eliezer studied under his father Joel haLevi of Bonn, as well as under Judah HeHasid and Judah ben Kalonymus of Mainz. His brother died a martyr's death in 1216. Eliezer's mourning for him was so great that his vision was impaired and he was compelled to dictate his novellae to his students.
His major work, ''Sefer Avi HaEzri'' (My Father is my Help), which is more commonly known by its author's acronym as ''Sefer Ra'avyah'' (also spelled ''Sefer Rabiah''),<ref>{{cite book|last=Trachtenberg|first=Joshua|author-link=Joshua Trachtenberg|orig-date=Originally published 1939|title=Jewish Magic and Superstition|publication-place=Philadelphia|publisher=University of Pennsylvania Press|publication-date=2004|page=318|isbn=9780812218626}}</ref> is a compendium of articles that he developed into a book. It contains halakhot and legal decisions.
