Book excerpt: Sometimes thought to be a bizarre Victorian custom, photographing corpses has been and continues to be an important, if not recognized, occurrence in American life. It is a photographic activity, like the erotica produced in middle-class homes by married couples, that many privately practice but seldom circulate outside the trusted circle of close friends and relatives. Along with tombstones, funeral cards, and other images of death, these photographs represent one way in which Americans have attempted to secure their shadows.
