I'm just beginning. I was enticed by Rott's Wiki entry - for example "Rott began to evidence persecutory delusions. In October 1880, while on a train journey, he reportedly threatened another passenger with a revolver, claiming that Brahms had filled the train with dynamite. Rott was committed to a mental hospital in 1881, where despite a brief recovery he sank into depression. By the end of 1883 a diagnosis recorded "hallucinatory insanity, persecution mania—recovery no longer to be expected." He died of tuberculosis in 1884, aged 25. Many well-wishers, including Bruckner and Mahler, attended Rott's funeral at the Zentralfriedhof in Vienna."
