Purim
There is a tale in the Hasidic Chabad movement that supposedly Joseph Stalin died as a result of some metaphysical intervention of the seventh Chabad leader, Rabbi Menachem Mendel Schneerson, during the recitation of a discourse at a public Purim Farbrengen. Stalin was suddenly paralyzed on 1 March 1953, which corresponds to Purim 1953, and died 4 days later. Due to Stalin's death, nationwide pogroms against Jews throughout the Soviet Union were averted, as Stalin's infamous doctors' plot was halted.
Joseph Meezon
Joseph Isaakovich Meezon (October 31, 1894 – February 10, 1938) was a Soviet Jewish Bundist politician. He was educated at Moscow State University. He joined the Communist Party of the Soviet Union in 1918 and started as Secretary of the District Committee. From August 1919 to September 1920 he was Chairman of the Vitebsk gubernatorial Committee. He was Secretary of the responsible Tula gubernatorial Committee from December 1920 to May 1923. During the Great Purge, he was arrested on October 10, 1937, sentenced to death by the Military Collegium of the Supreme Court of the USSR on February 8, 1938 and executed by firing squad two days later. After the death of Joseph Stalin, he was posthumously rehabilitated in 1955.
