1920. Keynes is undoubtedly one the most important figures in the entire history of economics. He revolutionized economics with his classic book, The General Theory of Employment, Interest and Money, which is generally regarded as the most influential social science treatise of the 20th Century, in that it quickly and permanently changed the way the world looked at the economy and the role of government in society. In The Economic Consequences of the Peace Keynes attacked the effects of the Versailles Settlement for its effects on Germany. His remarks, while probably correct, it also may have been the discomfort among the intellectual elite of the victor countries that contributed to a lack of resistance when Hitlerism took over Germany.
