Louis Sullivan And The Chicago Department Store: Long recognized as a Chicago landmark, the Carson Pirie Scott Building also represents a milestone in the development of architecture. The last large commercial structure designed by Louis Sullivan, the Carson building reflected the culmination of the famed architect's career as a creator of tall steel buildings. In this study, Joseph Siry traces the origins of the building's design and analyzes its role in commercial, urban, and architectural history. Copyright (C) Muze Inc. 2005. For personal use only.
