Jacques Etienne Chevalley de Rivaz, né le 16 août 1801 à Vevey mais demeurant à Paris, est à l'origine de la famille Chevalley de Rivaz par l'adjonction de son lieu d'origine à son patronyme. Ses grands-parents sont Jacques Etienne Chevalley (1738-1809) et Anne Chappuis, de Rivaz.
Jacques Etienne was appointed to be doctor to the King of Naples and his certificate of origin (passport) was issued by the Municipal Council of the Commune of Rivaz, near Vevey, in 1827. He lived at Casamicciola, on the island of Ischia, in the Bay of Naples. He became famous for his work during a cholera epidemic in Naples, when people were often dying of fright, and apparently, on one celebrated occasion, he got into the bed of a dying man, to show the people that cholera was not contagious. |
