American Tract Society Building
TWO COMPETING styles of architecture predominated in the United States when the American Tract Society Building was completed. The earlier style was Richardsonian Romanesque, named for Henry Hobson Richardson, critically considered to be our first native-born architect of world-class genius. Richardson combined the massive, lithic qualities of the Roman stone arch with his own uncanny sense of flowing, organic energy and balanced asymmetry. The other style, called Sullivanesque for Louis Henry Sullivan, represented a break with the past because it was an expression of the new tall building as a vertical design.
