Ragnar Frisch

Here is the revised memorial biography of Ragnar Anton Kittil Frisch, refined to retain only well-supported and verifiable facts:

Ragnar Anton Kittil Frisch was born on 3 March 1895 in Christiania (now Oslo), Norway, to gold- and silversmith Anton Frisch and Ragna Fredrikke Kittilsen (en.wikipedia.org). Initially apprenticed in his family’s trade with the renowned David Andersen workshop, Frisch pursued economics at the University of Oslo—choosing it for its perceived brevity and relative simplicity—and earned his degree in 1919 (en.wikipedia.org).

After completing his apprenticeship in 1920, he continued his academic formation by studying economics, mathematics, and statistics in France, England, and the United States during the early 1920s (encyclopediaofmath.org). He obtained his doctoral degree (dr.philos.) in mathematics and statistics from the University of Oslo in 1926 (encyclopediaofmath.org).

Frisch is credited with coining the term "econometrics" in 1926 to describe a field combining economic theory, mathematics, and statistical validation—a discipline he sought to develop as a strict empirical science (en.wikipedia.org). In 1933, he introduced the terms "microeconomics" and "macroeconomics" to distinguish between analysis of individual economic units and aggregate economic systems, respectively (en.wikipedia.org).

In 1930, Frisch co-founded the Econometric Society, and from 1933 to 1955 he served as the founding editor of its journal, Econometrica (ekonometria.org). After a visiting professorship at Yale University in 1930–31, he returned to Norway and in 1931 was appointed Professor of Economics and Statistics at the University of Oslo, where he established and directed the Institute of Economics from 1932 until his retirement in 1965 (encyclopediaofmath.org).

In 1969, Ragnar Frisch and Jan Tinbergen jointly received the inaugural Nobel Memorial Prize in Economic Sciences. The award cited their pioneering development and application of dynamic econometric models to analyze economic processes (nobelprize.org).

Ragnar Frisch passed away on 31 January 1973 in Oslo (en.wikipedia.org).
