This is an odd book. Not a bad one: but odd. It isn’t really about Schumann’s music, which is the first oddity, since his life without it is rather tiresome and not really the stuff of a serious biography. Odder still, it isn’t really about Schumann’s life either, though all the key facts of that short and not always glorious career are contained within its pages. It is most concerned with his decline, and his death, and concerned about them to one particular end: to prove that Schumann, long portrayed as the ultimate Romantic who died after a mental collapse brought on by melancholia, in fact died of tertiary syphilis.
