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.
The Death of Stalin
The Radio Moscow portion is a retelling of an apocryphal story first recorded in Solomon Volkov's book "Testimony". However, as told by Volkov, it was Maria Yudina who was woken up in the middle of the night to be brought in to record, and the recording brought Stalin to tears, moving him to pay Yudina 20,000 rubles in appreciation. The story subsequently served as the loose basis for the 1989 BBC radio play "The Stalin Sonata" written by David Zane Mairowitz.
