I am out of clues. It's a 1936 photo of Isaac Diller, the neighbor who played with the Lincoln boys and actually knew Fido. Diller was 82 in 1936. Here is another photo of a young Diller:
The movement in that previous picture I posted was described by Carl Sandburg as follows: "A squeaking farm wagon coming down the side street caused the lad on the sidewalk (Diller) to turn his head while the picture was being taken."
What famous novelist had actually considered returning home from vacation in Europe aboard the Titanic (but boarded a less expensive ship instead)? During his career he had interviewed Robert Todd Lincoln.
Thanks, Bill! It's interesting to know that taking a less expensive ship may have saved Dreiser's life. On the other hand, if he did survive the disaster, he would have probably written a wonderful novel about it. Is the Robert Lincoln interview still available?
Dreiser wrote Sister Carrie which was made into a film called Carrie starring Laurence Olivier and Jennifer Jones, and An American Tragedy.
