Poppers (Popers), Jacob ben Benjamin Hakohen


POPPERS (Popers), JACOB BEN BENJAMIN HAKOHEN (d. 1740), German rabbi. Born in Prague, Poppers studied under his father and in various yeshivot. He was subsequently appointed rabbi of Coblenz and of Trier, in the Rhineland. He declined an invitation to Halberstadt in 1718 but accepted the rabbinate of Frankfurt where he headed a large yeshivah. His disciples included Jacob Berlin, Joseph *Steinhardt, and Joseph Wassertrilling. Poppers corresponded with the great scholars of his time on halakhic and contemporary problems. He was among those who imposed a ban on Moses Hayyim *Luzzatto in 1725 for teaching Kabbalah and on suspicion that he adhered to the Shabbatean doctrine. Compelled to leave Italy, Luzzatto arrived in Frankfurt, where he was summoned before the bet din of Poppers and, after much discussion, was obliged again to promise not to teach Kabbalah nor to engage in its study until he was 40 years old. Poppers was the author of Shav Ya'akov (Frankfurt, 1741–42), responsa in two parts. Some of his novellae are included in Minḥat Kohen (Fuerth, 1741) by Shabbetai b. Moses. Poppers died in Frankfurt.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
