My main graduate training was received at the University of Chicago from which I received the Ph.D. in 1938.
Even before I came to Chicago, I had gotten interested in the existence of dispersion of prices under conditions which economic theory said would yield a single price.
I met my wife, Margaret L. Mack, at the University of Chicago. We were married in 1936. She died in 1970.
In 1958, I came to Chicago where I have remained.
