Wow. I think this is one of the few times I haven't had to give a clue for a question. Joe is correct that this is a younger Wayne "Doc" Temple, who in February turned 95. I found this picture in the University of Illinois website, but I have to admit that a desire to brag just a bit prompted this question. This year the University of Illinois Press published Doc's dissertation that he wrote in 1956 on Noah Brooks, finishing it after the death of his original advisor James G. Randall. Michael Burlingame wrote the introduction to the book and cited in one of the footnotes the article yours truly wrote on Randall and Carl Sandburg. I found it humbling to be mentioned in the same citation as Temple and Harry E. Pratt.
