In a seminal article entitled “The Development of Theatre on the American Frontier, 1750–1890,” published in the May, 1978, issue of Theatre Survey, Douglas McDermott began synthesizing information about the nineteenth-century American theatre available in books, journals, theses, dissertations, and unpublished primary sources. His thesis of a three-phase development of American frontier theatre—consisting of small and strolling troupes, then standard repertory companies in small towns, and finally resident urban companies—must now be tested and modified by detailed examinations of particular stars, families, and companies touring in provincial America. This study of the Jefferson company corrects, supports, and expands McDermott's theory with evidence about one group of American actors who trouped, in various combinations, through the East, Mid-West, and South from 1830 to 1845.
