About

Technological innovations in steel manufacturing enabled taller buildings to be built with fireproof floors and fast-moving elevators. Louis Sullivan, one of Chicago’s influential architects, most successfully employed the new steel technology, using terra cotta ornament to define the steel framing. Minneapolis architects adopted many of Sullivan’s design techniques for their larger commercial commissions in the downtown district. Recognized as precursors to the steel-and-glass skyscrapers, these Chicago Commercial buildings provide an important link to the nineteenth century.
