From the days in the mid-nineteenth century when the intrepid Margaret LaForge worked as the first lady boss of Macy's Department Store, women have been present in the work force as business managers, but never in significant numbers.1 In recent years, however, a convergence of legal, educational, demographic, and social developments have begun to move women into the mainstream of corporate management. This review essay analyzes the present state of research primarily from the United States on women as managers in business, commerce, and industry. As with many subjects dealing with the study of women, research on this one both benefits and suffers from falling between the territorial definitions of the disciplines. The subject is divided among a range of fields and subspecialties: industrial psychology, business administration, human resource development, industrial education, sociology, communications, management, and organizational psychology. Recently, there has been a rapid increase in research, more integrative work, and the emergence of a visible, major body of literature.2
