"The Chicago, group... owes its origins to Professor Frank H. Knight of the University of Chicago, who is Mises’s junior by a few years. Like Mises, Knight owes his original reputation to a theoretical monograph; notwithstanding an early lack of recognition, the latter’s Risk, Uncertainty and Profit (1921) eventually became, and for many years continued to be, one of the most influential textbooks on economic theory, although it had not originally been designed as such. Knight has since written a great deal on questions of economic policy and social philosophy—mostly in articles the majority of which have since been published in book form. The best-known, and perhaps also the most characteristic, volume is The Ethics of Competition and Other Essays (1935). Knight’s personal influence, through his teaching, exceeds even the influence of his writings. It is hardly an exaggeration to state that nearly all the younger American economists who really understand and advocate a competitive economic system have at one time been Knight’s students."
