The Fellowship of Econometrics: Selection and Diverging Views in the Province of Mathematical Economics, from the 1930s to the 1950s.

An essay on the views of members of the Econometric Society between the early 1930s and through the 1950s is presented. The article attempts to identify and analyze a coexistence among members of the society with divergent views on econometrics and the application of mathematics. The article discusses conflict during the early 1930s when the founding members of the society were selecting its first fellows, and in the 1950s involving economist Oskar Morganstern.
