Charles K. Zeilman is my husband's g-g-uncle. He was the younger brother of my husband's great-grandfather, John Zeilman. I was at my husband's grandfather's house yesterday, trying to locate a newspaper article with photo from 1922, reporting Charles' graduation from the U. of Illinois. He went on to teach at the U. of Birmingham in 1924-1925, then for some reason, went home to the Albany, NY area, married, and settled there.
[I just discovered the info about the U. of Birmingham. He's listed with other faculty on their website.]
I did find a photo of him as an older man. Caption on the back says, "Prof. C.K. Zeilman".
