The impetus for the conference that was the basis for this volume emanated from the influence of two brilliant minds-Egon Sohmen and Adam Klug, who both died at an early age, leaving their families and the professions of economics and economic history with major voids. In the course of research on the origins of Open Economy Macroeconomics, the significant contributions of Egon Sohmen came to the fore. After correspondence with some of those involved in the early development of the Open Economy Macromodel, we turned to Adam Klug for his views on the matter-as he had dealt with the history of intertemporal trade models in his Ph. D. thesis. And it was Adam who suggested the idea of a conference bringing together economists and economic historians. At this point we want to acknowledge the very generous grant from the Egon Sohmen Foundation and the active participation of Dr. Helmut Sohmen and Mrs. Renee Sohmen at the conference. We also want to thank Prof. Sir Aaron Klug, Nobel Laureate, and the Klug family for their support and the financial contribution of the Adam Klug Memorial Lecture Fund at Ben Gurion University. Other institutions that contributed to the conference were the Gianni Foundation; Bank of Israel; University of North Carolina; Department of Economics, Faculty of Social Science and Aharon Meir Center for Banking, Bar Ilan University; Department of Economics and Faculty of Social Science, Ben-Gurion University of the Negev.
