Chicago in the 1890s was home to two remarkable institutions, started by two remarkable activist-philosophers, experimenting with ideas and with social change. The first was Hull House, a social settlement, founded by Jane Addams and Ellen Gates Starr in 1889. The second was the Laboratory School, an experimental school opened in 1896 by John Dewey, along with teachers Katherine Camp Mayhew and Anna Camp Edwards. Interaction was constant between the residents of Hull House and the teachers of the Laboratory School, as the participants learned from and taught each other. Through Hull House and the Laboratory School, Addams and Dewey formulated, tested, and enacted central tenets of classical American pragmatism.
