What killed Mozart?
Mozart’s sister-in-law, the authors note, said that his body became so swollen during his fatal illness that he could not turn in bed. His cause of death in a Viennese death registry was “hitziges Frieselfieber,” or fever and rash.
But all of these things — swelling, fever, rash — are symptoms that don’t tell us what the underlying disease was. Speculation since the time of Mozart’s death has ranged from poisoning, to syphilis, to trichinosis from eating undercooked pork chops.
