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.
Keke Geladze
Geladze died on 4 June 1937. The medical report listed the cause of death as heart failure. Occupied with the Great Purge of Communist officials and the Red Army, in particular the arrest and interrogation of Mikhail Tukhachevsky, Stalin did not attend the funeral; Beria was sent in his stead, with a wreath that had the message "To a dear and beloved mother, from your son Iosif Jughashvili (Stalin)" written in Georgian and Russian. Stalin had her buried in the Mtatsminda Pantheon overlooking Tbilisi, a necropolis full of prominent Georgian figures.
