From Pierre-François Puech:

Re: Small “epidemic” may have killed Mozart (Aug. 17): Please have a look here. you will read the following text:

Mozart’s Death - Murder, Accident or Disease? Accident A couple of investigators have surprisingly broken from the norm of attributing Mozart’s death to murder and strange ailments by announcing that Mozart died from complications arising from accidents.

The first to push this story was French anthropologist Pierre-Francoise Puech, who claimed to have positively identified a skull at Salzburg’s Mozarteum to be that of Mozart. Puech drew attention to a fracture in the skull, claiming that it had been sustained from one of Mozart’s many falls in 1791, and that it had caused a chronic bruising that had eventually put Mozart in a coma and killed him. The skull was supposed to have been rescued by a gravedigger named Joseph Rothmayer during the reorganisation of the composer’s grave, who later gave it to the Salzburg Mozarteum. Three years later, the American physician Niles E. Drake concurred with Puech’s theory in an article that was published in the journal BioScience. This theory would indeed help explain why Mozart was depressed and dizzy not long before his death.

The obvious problem with this theory is that there is still no consensus as to whether the skull actually belonged to Mozart. Rothmayer had allegedly wrapped wire around the neck of Mozart’s corpse before burying it, and had retrieved the skull ten years later when it was exhumed. Research had concluded that the skull belonged to a 20-40 year old South German male who suffered a developmental abnormality called premature synopsis of the metopic suture (PSMS). This abnormality is characterised by the bone of the forehead developing in two halves, and the failure of the metopic suture to close after birth, resulting in a broad midface and a small, abnormally-shaped skull. As Mozart’s portraits depicted a straight, vertical forehead, bulbous nose, prominent cheekbones and upper lip, and prominent brow arches, it was supposed that the skull did indeed belong to him. Further research involving the superimposition of a photograph of the cranium of the skull on portraits of Mozart painted between 1778 and 1788 indicated conformity with all side proportions of the head.

However, Nova Scotian neurologist Professor TJ Murray, who founded the Dalhousie Society for the History of Medicine, denied that the skull was that of Mozart as seen in portraits. Walter Brauneis, archivist of the Office for the Preservation of Historical Monuments in Austria, undertook to carry out his own research by locating official medical records concerning Mozart’s death. Surprisingly he found a doctor’s description of the body, which noted that Mozart (the dentist’s worst nightmare!) had only seven teeth remaining in his mouth (the rest having rotted or fallen out!) When the Mozarteum skull was re-examined, it was found to have four more teeth than had been recorded by the doctor. Puech supporters countered that the doctor probably counted only the healthy teeth.

The only way to be sure just whose skull it is would be to perform DNA analysis on the skull; unfortunately, all of Mozart’s children died childless, and it would be unwise to disturb his parents’ grave.

My comment is that one must first read the above comments, and go on google at Puech, P. F. , Mozart.
