Schoenberg's superstitious nature may have triggered his death. The composer had triskaidekaphobia (the fear of the number 13), and according to friend Katia Mann, he feared he would die during a year that was a multiple of 13 (quoted in Lebrecht 1985, 294). He dreaded his sixty-fifth birthday in 1939 so much that a friend asked the composer and astrologer Dane Rudhyar to prepare Schoenberg's horoscope. Rudhyar did this and told Schoenberg that the year was dangerous, but not fatal.

But in 1950, on his seventy-sixth birthday, an astrologer wrote Schoenberg a note warning him that the year was a critical one: 7 + 6 = 13 (Nuria Schoenberg-Nono, quoted in Lebrecht 1985, 295). This stunned and depressed the composer, for up to that point he had only been wary of multiples of 13 and never considered adding the digits of his age. He died on Friday, 13 July 1951, shortly before midnight. Schoenberg had stayed in bed all day, sick, anxious and depressed. His wife Gertrud reported in a telegram to her sister-in-law Ottilie the next day that Arnold died at 11:45 pm, 15 minutes before midnight (Stuckenschmidt 1977, 520). In a letter to Ottilie dated 4 August 1951, Gertrud explained, "About a quarter to twelve I looked at the clock and said to myself: another quarter of an hour and then the worst is over. Then the doctor called me. Arnold's throat rattled twice, his heart gave a powerful beat and that was the end" (Stuckenschmidt 1977, 521).
