Today he is still well known for his ground breaking work with children and adolescents. Hall very much helped to start the developmental thread of psychology in America. He also employed surveys and statistics in his studies; a method started by Galton. During Phyllis Blanchard's era, he was the president of Clark University as well as a professor there. Blanchard clearly was influenced by Hall, and chose to work in many of the same areas he did, especially the period of adolescence. Hall seemed to have respected Blanchard as well, which is reflected in the introduction he wrote for her book The Adolescent Girl. This book contains many references to Hall's two volume work, Adolescence: Its Psychology, and Its Relations to Physiology, Anthropology, Sociology, Sex, Crime, Religion, and Education.
