The third dimension in social casework: Mary E. Richmond's contribution to family treatment

This article traces the development of family group treatment as conceptualized by Mary E. Richmond (1861–1928). While the main course of social work was following the new individual psychology from Europe after World War I, Richmond was paving the path for a clinical approach that was not to be realized until 30 years later.This is a revised, abbreviated version of a presentation made by the author at a doctoral seminar on the casework roots of practice delivered in 1965 at the School of Social Work, University of Southern California.
