Carl Menger, the founder of the Austrian School, is just as relevant today as ever. He died 94 years ago today in 1921.
Joseph Salerno sums it up:
Despite the many illustrious forerunners in its six-hundred year prehistory, Carl Menger (1840-1921) was the true and sole founder of the Austrian school of economics proper. He merits this title if for no other reason than that he created the system of value and price theory that constitutes the core of Austrian economic theory. But Menger did more than this: he also originated and consistently applied the correct, praxeological method for pursuing theoretical research in economics. Thus in its method and core theory, Austrian economics always was and will forever remain Mengerian economics.
