The Former Chicago Historical Society Building is a historic landmark located at 632 N. Dearborn Street on the northwest corner of Dearborn and Ontario streets near downtown Chicago. Built in 1892, the granite-clad building is a prime example of Henry Ives Cobb's Richardsonian Romanesque architecture.[1] Henry Cobb designed this home for Walter Loomis Newberry, founder of the Newberry Library in Chicago. The building was designated a Chicago Landmark in 1997. It was listed on the National Register of Historic Places in 1978, under the name, Old Chicago Historical Society Building.
