Let’s begin w/the pic that intrigued 1000s & CNN. Found it in a used book abt 15 yrs ago. No, don’t remember what book. Looked at pic often & asked myself—tried to ask them—who they were. Yes, I’m a historian, but it wasn’t professional curiosity. A sense of shared humanity. 1/ I tweeted it, hoping to find its owners. Many ppl kindly rt’d it. Some ppl got VERY involved in trying to help. One person digitally restored it. Another found a set of the same bookends on eBay. Another figured out what national park was in the photo on the wall. And so on. 2/
