A Swedish physicist can not discuss his work with fifty people unless he goes abroad. A Swedish economist can get opinions and instructions in his native language from thousands upon thousands of his fellow citizens.

I met my wife, Margaret L. Mack, at the University of Chicago. We were married in 1936. She died in 1970.
