The University of Chicago Sociology department was established in 1892, three years after Hull House was established (1889). Members of Hull House welcomed the first group of professors, who soon were "intimately involved with Hull House" and assiduously engaged with applied social reform and philanthropy" In 1893, for example, faculty (Vincent, Small and Bennis) worked with Jane Addams and fellow Hull House resident Florence Kelley to pass legislation "banning sweat shops and employment of children" Albion Small, chair of the Chicago Department of Sociology and founder of the "American Journal of Sociology", called for a sociology that was active "in the work of perfecting and applying plans and devices for social improvement and amelioration," which took place in the "vast sociological laboratory" that was 19th-century Chicago. Although, untenured, women residents of Hull House taught classes in the Chicago Sociology Department. During and after World War I the focus of the Chicago Sociology Department shifted away from social activism toward a more positivist orientation. Social activism was also associated with communism and a "weaker" woman's work orientation. In response to this change, women sociologists in the department "were moved inmasse out of sociology and into social work" in 1920 The contributions of Jane Addams and other Hull House residents were buried in history.
