These two photos have no information attached. I believe the man on the left in the first photo is Merritt Sarles, one of Walter’s graduate school classmates at Hopkins and later a co-worker at US Industrial Chemicals. Walter is on the right. The second photo shows Walter standing in front of the USI lab.

It is difficult to find photos of Walter without a cigar.
