Rabbi Yitzchak Zilber zt’l was a legendary leader of Russian Jewry for over three decades. He remained resolutely firm in his faith and practiced Torah and mitzvos throughout his arduous years behind the Iron Curtain, even in the brutality of a Russian Labor Camp. His autobiography, To Remain a Jew is his incredible account of how he remained faithful to G-d even under the most trying circumstances. The following is just one anecdote recorded in the book:
This rediscovered treasure was the project of Rabbi Menachem Mendel Schneerson, which he compiled in 1943 as a calendar and in 1944 as an encyclopedia, as instructed by his father-in-law, Rabbi Joseph Isaac Schneerson, the sixth Chabad Rebbe, whom he later succeeded as Rebbe in 1950.
