It is a fact of life that disasters were part of our forefather’s lives as much as they are ours. Often times our ancestors did nothing to warrant a mention in the newspapers unless they were tied to a disaster of some sort.
So was the case of my own relative, Jesse Koppenhafer, who had the misfortune of carrying a defective lamp into the Luke Fidler mine 29, November, 1902. The resulting explosion claimed the lives of seven men, Jesse included. It was later concluded the light Jesse carried was defective. Other articles I read indicated that much of the equipment used by the miners was not safe.
If you have a relative that was involved in an accident in Pennsylvania or another state, you might want to look over the many disasters listed at GenDisaster. The site is broken down by state and type of accident.
