German rabbi; born at Prague in the middle of the seventeenth century; died at Frankfort-on-the-Main in 1740. His father, who was a distinguished Talmudist, instructed him in rabbinical literature, in which he acquired great proficiency. He was successively rabbi at Coblenz, Treves, Halberstadt, and in 1718 he was called to the rabbinate of Frankfort-on-the-Main.
Poppers was the author of two works: "Shab Ya'aḳob," containing responsa divided into two volumes (Frankfort-on-the-Main, 1742), and "Ḥiddushim," Talmudical novellæ inserted by Shabbethai ben Moses in his "Minḥat Kohen" (Fürth, 1741).
