The leader of the Second Viennese School, Arnold Schoenberg (shown in the picture above with his wife Gertrud and their daughter Nuria) had triskaidekaphobia, a rare fear of the number 13. Schoenberg was born on the 13th of September and always considered this number to be a bad sign.
Arnold also had to rename his opera, Moses und Aaron (in the picture below). He called it, Moses und Aron so that the number of letters wouldn’t equal 13.

In the end, Arnold died on the 13th of July, 1951. He spent all day lying in bed and waiting for death to come. His wife tried to convince him to get up but he refused to and died at 11:37 PM saying, “harmony”.
