Charles F. Roos

Charles Frederick Roos (May 18, 1901 – January 6, 1958) was an American economist who made contributions to mathematical economics. He was one of the founders of the Econometric Society together with American economist Irving Fisher and Norwegian economist Ragnar Frisch in 1930. He served as secretary-treasurer during the first year of the society and was elected as president in 1948. He was director of research of the Cowles Commission from September 1934 to January 1937.

Roos earned a PhD in mathematics from Rice University in 1926, under supervision of Griffith C. Evans. He was amongst the first, together with Evans and mathematician Frank P. Ramsey, to use the calculus of variations in mathematical economics. His direct involvement with two key institutions in economic history, both the Econometric Society and the Cowles Commission, place him in a pivotal position in the mathematization of economics in the first half of the 20th century. His own work, however, would not be so influential. Mathematical economics and econometrics eventually favored technical and epistemological approaches that were different from his own.
