My early education was in the public school system of Omaha, where, retrospectively, I realize that my high school training served me in good stead for the basic subjects of mathematics, English, foreign languages and history.

The completion of my undergraduate training at the University of California (Berkeley) provided just the needed touches of rigor at advanced levels in both economics and mathematics.

An early fascination with higher mathematics at the university level blossomed into speculative thinking that could provide a basis for dealing with economic issues.

Although I was not aware of it at the time, the experience of growing up during the Great Depression was to have a profound impact on my intellectual and professional career.

I, Lawrence Klein, was born in Omaha, Nebraska, as were my elder brother and younger sister.

After my first visit to Japan, in 1960, to work on a joint model building project at Osaka University, I maintained a continuing interest in the country and the entire Far East.

During the early 1960s, I decided to supplement research support for quantitative economic studies at Pennsylvania by selling econometric forecasts to private and public sector buyers.
