When Boas retired in 1937, most of his students considered Ruth Benedict to be the obvious choice for the head of the anthropology department. However, the administration of Columbia was not as progressive in its attitude towards female professionals as Boas had been, and the university President Nicholas Murray Butler was eager to curb the influence of the Boasians whom he considered to be political radicals. Instead, Ralph Linton, one of Boas's former students, a World War I veteran and a fierce critic of Benedict's "Culture and Personality" approach, was named head of the department. Benedict was understandably insulted by Linton's appointment and the Columbia department was divided between the two rival figures of Linton and Benedict, both accomplished anthropologists with influential publications, neither of whom ever mentioned the work of the other.
