 At Chicago, Dewey founded The Laboratory School, which provided a site to test his psychological and educational theories. Dewey’s wife Alice was the school’s principal from 1896–1904. Dewey became active in Chicago’s social and political causes, including Jane Addams’ Hull House, and Addams became a close personal friend of the Dewey’s. Dewey and his daughter and biographer Jane Dewey credited Addams with helping him develop his views on democracy, education, and philosophy; nevertheless, the significance of Dewey’s intellectual debt to Addams is still being uncovered (“Biography of John Dewey”, Dewey 1939a; see also Seigfried 1999, Fischer 2013).
