Two of my students using the Spengler Papers at Duke have asked that I 
post the following query to the list:

Albert B. Wolfe was an economics professor at Ohio State University. He 
apparently was an institutional economist and demographer, and was 
Joseph J. Spengler's thesis adviser (1930). Correspondence between Wolfe 
and Spengler from 1937 makes mention of Wolfe's projected retirement in 
ten years. 

Might anyone know anything about Wolfe? For instance, what type of 
population work Wolfe had done and whether that work linked to studies 
of French de-population, Spengler's concern in the 1930s?
