On his return to the United States, Linton took a position at the University of Wisconsin–Madison, where the Department of Sociology had expanded to include an anthropology unit. Linton thus served as the first member of what would later become a separate department. Several of his students went on to become important anthropologists, such as Clyde Kluckhohn, Marvin Opler, Philleo Nash, and Sol Tax. Up to this point, Linton had been primarily a researcher in a rather romantic vein, and his years at Wisconsin were the period in which he developed his ability to teach and publish as a theoretician. This fact, combined with his penchant for popular writing and his intellectual encounter with Radcliffe-Brown (then at the University of Chicago), led to the publication of his textbook "The Study of Man" (1936). It was also during this period that he married his third wife, Adelin Hohlfeld, who worked as his secretary and editor as well as his collaborator—many of the popular pieces published jointly by them (such as "Halloween Through Twenty Centuries") were in fact entirely written by Adelin Hohlfield.
