Years ago, when the worldwide web was new, I had a tiny little non-blog at Columbia, and on it I posted a scan of this photo of my grandfather. I’d made the scan in the school’s computer lab; scanning machines were then exciting and new, and it felt vaguely like theft of technology for me to use it for such a merely personal purpose. Reading through some old family letters this morning, I thought of the photo again, and decided I’d make a new scan, on our home scanner, whose technology is probably fourteen generations better than the machine I used twenty years ago. My guess is that the photo itself was taken in the 1930s, but I’m not sure.
