Ghosts from the Past: While working on the WWI record of serviceman Hugh Edmiston, Jr., a staff member in the St. Louis…
Fire. Sometimes things get destroyed by an act of God (or vandals, I’ll have to poke into it and see if the cause of the famous fire at the St. Louis records center was ever publicly admitted).
It’s extremely fortunate that this photo’s image transferred to the adjacent document. The file the photo was housed in was damaged by water in the 1973 fire at the National Personnel Records Center. The photograph itself was an entire loss, with a complete and total removal of the emulsion. Without this ghostly image transfer, we would have no image at all and only a blank photographic mount. Now with the help of digital technology used by our Reformatting Lab, we can capture and preserve the image even though the original photograph was lost.
