The Historical Society of Oak Park and River Forest was organized in 1968 to operate a Museum, Archives, and Research Center on behalf of the sister villages of Oak Park and River Forest, Ill.

Located on the second floor of the National Historic Landmark Pleasant Home since 1970, the organization is a 501(c) 3 not-for-profit which serves the community by preserving and making accessible artifacts, photographs, documents, and other material that tell stories about the rich heritage of our community.
