1817 - 1896 (21 Adar 5656) ISAAC ELCHANAN SPECTOR (Kovno, Russia)
Considered the leading Russian rabbinic scholar of his day. Spector, who was active in many aspects of Jewish life, was a supporter of the Hovevei Zion movement, declaring it a mitzvah (religious duty) to settle in Eretz Israel. He fought for the right of Jewish soldiers to obtain kosher food and against a ban on ritual slaughter proposed by the Russian government. His considerable responsa were published in three parts: Beer Yitzchok, Nachal Yitzchok, and En Yitzchok (the Well, Stream, and Spring of Isaac).
