Here Emigholz presents the buildings of Louis Sullivan. “All buildings have arisen, have stood, and stand as physical symbols of the psychic state of the people . . . throughout the past and the present, each building stands as a social act,” Sullivan wrote in the 1906 essay ‘What Is Architecture.' “In everything that men do they leave an indelible imprint of their minds. If this suggestion be followed out, it will become surprisingly clear how each and every building reveals itself naked to the eye; how its every aspect, to the smallest detail, to the lightest move of the hand, reveals the workings of the mind of the man who made it, and who is responsible to us for it.”
