It was not until I got my first job, at the University of Washington in Seattle, and began playing chess with Don Gordon, a brilliant young theorist, that I learned economic theory.

While I was there I became deeply interested in photography, and indeed the most noteworthy event in my early life was winning first, third, fourth and seventh prizes in an international competition for college and high school students.

My father had not even completed high school when he started as an office boy working for the Metropolitan Life Insurance Company, and I am not sure that my mother completed high school.

Our family life was certainly not intellectual.
