Countess Di Bandi
Dr. Jan Bondeson, a senior lecturer at the Cardiff University School of Medicine and the author of a 1997 book titled A Cabinet of Medical Curiosities, said that one of the relatively well-documented early cases of spontaneous human combustion happened in 1731, involving the Countess di Bandi of Cesena, Italy.
There were some similarities between her case and that of Mary Reeser. The noblewoman also was consumed by flames, seemingly without an external source, leaving only her legs and greasy bad-smelling sticky substance.
