The Carson Pirie Scott Store, located in Chicago, was designed by the renowned architect Louis Sullivan in 1899. Sullivan is often regarded as the father of modernism in architecture due to his innovative use of ornamentation and structural design.
The building is notable for its iron and glass façade, which marks an important step toward modern skyscraper design. Sullivan's design broke away from traditional architectural forms, embracing functional aesthetics.
While Mies van der Rohe, William Le Baron Jenney, and Richardson were all influential architects, the Carson Pirie Scott Store is most closely associated with Louis Sullivan.
