Abstract
This paper will trace the history of DVI from nineteenth-century practices of sight recognition to contemporary DVI, detailing when and how different technologies used in DVI entered the disaster morgue. Much of this history is defined by improvisation, as local communities affected by sudden, mass death often relied on known technologies, medical or otherwise, applied under extremely difficult circumstances. Initially, these technologies were not always strictly forensic, but ones that supplemented sight recognition. As more forensic technologies became available in others fields, such as criminology, dentistry, and forensic pathology, disaster responders had greater tools at their disposal. The gradual introduction of these tools allowed DVI to become a more systematic and scientific process.
