Irving Fisher, 1867-1947.

Irving Fisher was one of the earliest American Neoclassicals of unusual mathematical sophistication.  He made numerous important contributions to the Neoclassical Marginalist Revolution, of which the following are but a sample:

(1) his contributions to the Walrasian theory of equilibrium price (he also invented the indifference curve device) in 1892;
(2) his volumes on the theory of capital and investment (1896, 1898, 1906, 1907, 1930) which brought the Austrian intertemporal theories into the English-speaking world, wherein he introduced the famous distinction between "stocks" and flows", the Fisher Separation Theorem and the loanable funds theory of interest rates.
(3) his famous resurrection of the Quantity Theory of Money (1911, 1932, 1935);
(4) the theory of index numbers (1922);
(5) the Phillips Curve (1926)
(6) his debt-deflation theory (1933) which is echoed in Post Keynesian economics.

This Yale economist was an eccentric and colorful figure.  When Irving Fisher wrote his 1892 dissertation, he constructed a remarkable machine equipped with pumps, wheels, levers and pipes in order to illustrate his price theory - see here for pictures of his draft and his first and second prototypes.  Socially, he was an avid advocate of eugenics and health food diets.   He  made a fortune with his visible index card system - known today as the rolodex - and advocated the establishment of an 100% reserve requirement banking system   His fortune was lost and his reputation was severely marred by the 1929 Wall Street Crash, when just days before the crash, he was reassuring investors that stock prices were not overinflated but, rather, had achieved a new, permanent plateau.
