I did a little googling, and apparently this guy lived in the 6300 block of Artesian. I lived on the other side of Devon, in the 6400 block of Maplewood, just a couple blocks away.
I was up in the old neighborhood in August, and it's nothing like when I grew up there in the '50s and '60s. Used to be all Jewish businesses along Devon Avenue, now it's all Indian and Pakistani. Totally unrecognizable.
We used to go to the synagogue on the 6200 block of Artesian. (I don’t think it is a synagogue anymore).
