Fisher (1867-1947) graduated and took his PhD at Yale (the doctoral dissertation, Mathematical Investigations in the Theory of Value and Prices, was reviewed by Harrod), where he began teaching mathematics while still in graduate school until 1895. He then transferred to the Department of Political Economy as an assistant professor in political and social science and became full professor in 1898; he retired in 1935. He was a prolific writer (his bibliography lists about 2000 titles), particularly interested in monetary theory and stabilization policy, in mathematical economics and econometrics (he was the first president of the Econometric Society, 1931-33), and was a zealous reformer, in economics as in other causes.
