My grandpa retired before I was born, so I didn't really expect to find anything online. The first hit was a direct one at at the Forestry History Society. It turns out I could get a copy of my grandpa's biography file by mail for free. Cool.
In response to my file request, the Society's archivist wrote:
Unknown pictures of my grandpa appearing 4 decades after his retirement and over 1 after his death? Really cool! But only imagined. When I looked at the files with the man, I didn't see my grandpa. Then I clicked on the other images.
If you search the Quick Search box of our Image Database for your grandfather, you can find 6 photographs that were taken by him. Two show images of what appears to be the same man. Your grandfather, perhaps?
And there stood my dad in 1940s knit skater's cap and tiny bomber jacket. He was a little younger than Ranger is now.
Cheryl, the archivist, sent me the full scan of the negative and I had new prints made for my dad, Ranger, and myself.
Behold, ghosts in the machine.
