Composer Arnold Schoenberg was fascinated with numerology. Born on Sept. 13, he came to fear that he would die at age 76, because its digits add to 13. He examined a calendar for 1951 and was dismayed to see that July 13 fell on a Friday. When the fateful day came he took to his bed, fearing the worst. The day passed uneventfully, and shortly before midnight his wife entered the bedroom to say goodnight. Schoenberg uttered the word “harmony” and died.

The time of his death was 11:47 p.m., 13 minutes before midnight on Friday, July 13, in his 76th year.
