The Association of Medical Superintendents of American Institutions for the Insane was organized in Philadelphia in October, 1844, the first professional medical specialty organization in the United States. The name of the organization was changed in 1892 to The American Medico-Psychological Association to allow assistant physicians working in mental hospitals to become members. In 1921, the name was changed to the present American Psychiatric Association (APA).
