Spontaneous human combustion (SHC) describes reported cases of the burning of a living (or very recently deceased) human body without an apparent external source of ignition.
In December 1966, the body of 92-year-old Dr. J. Irving Bentley was discovered in his Pennsylvania home by a meter reader. Actually, only part of Dr. Bentley’s leg and slippered foot were found. The rest of his body had been burned to ashes. A hole in the bathroom floor was the only evidence of the fire that had killed him; the rest of the house remained perfectly intact.
How could a man catch fire — with no apparent source of a spark or flame — and then burn so completely without igniting anything around him? Dr. Bentley’s case and several hundred others like it have been labeled “spontaneous human combustion” (SHC). Although he and other victims of the phenomenon burned almost completely, their surroundings, and even sometimes their clothes, remained virtually untouched.
Can humans spontaneously burst into flames? A lot of people think spontaneous human combustion is a real occurrence, but most scientists aren’t convinced.
In this article, we will look at the strange phenomenon of spontaneous human combustion, see what believers have to say about it and try to separate the scientific truth from the myths.
Spontaneous combustion occurs when an object — in the case of spontaneous human combustion, a person — bursts into flame from a chemical reaction within, apparently without being ignited by an external heat source.
The first known account of spontaneous human combustion came from the Danish anatomist Thomas Bartholin in 1663, who described how a woman in Paris “went up in ashes and smoke” while she was sleeping. The straw mattress on which she slept was unmarred by the fire. In 1673, a Frenchman named Jonas Dupont published a collection of spontaneous combustion cases in his work “De Incendiis Corporis Humani Spontaneis.”
The hundreds of spontaneous human combustion accounts since that time have followed a similar pattern: The victim is almost completely consumed, usually inside his or her home. Coroners at the scene have sometimes noted a sweet, smoky smell in the room where the incident occurred.
What makes the charred bodies in the photos of spontaneous human combustion so peculiar is that the extremities often remain intact. Although the torso and head are charred beyond recognition, the hands, feet, and/or part of the legs may be unburned. Also, the room around the person shows little or no signs of a fire, aside from a greasy residue that is sometimes left on furniture and walls. In rare cases, the internal organs of a victim remain untouched while the outside of the body is charred.
Not all spontaneous human combustion victims simply burst into flames. Some develop strange burns on their body which have no obvious source, or emanate smoke from their body when no fire is present. And not every person who has caught fire has died — a small percentage of people have actually survived what has been called their spontaneous combustion.
