Albert Kahn, who designed the airy and expansive concrete-frame “daylight factory” Ford plant in Highland Park, Mich. (top), created a similar West Lawn factory that was turned into Ford City Mall (bottom).
Clean lines and symmetry of ancient Greek and Roman temples inspired the design of the State Capitol in Richmond, Va. (left), and became hallmarks of many government buildings, including Chicago's City Hall (right).
In Boston, 19th-century architect H. H. Richardson’s Trinity Church spawned a distinctive style mimicked in myriad places of worship and public buildings. It’s evident in Chicago's former historical society, now Castle nightclub on Dearborn.
In stark contrast to tightly compartmentalized Victorian houses of the day, the Prairie Style Robie House (top) in Chicago helped pave the way for the more horizontal, open style of the modern ranch home (bottom).
The Wainwright Building in St. Louis (left) was one of the first skyscrapers to revel in its height and emphasize its thin, metal frame instead of hiding it. Its soaring, continuous piers are taken to a new height by Chicago's Aon Center (right).
The Pritzker Pavilion looks like the Disney Concert Hall in L.A. (left), both designed by Frank Gehry. His imagination and his reliance on computer-assisted design influenced the look of other structures, including Michigan Avenue’s Spertus Institute.
Robert Venturi’s postmodern style embraces complexity and contradiction, illustrated by a scale-thwarting pediment tacked onto the Philadelphia home (left) he designed for his mother. Similar touches can be seen in the skyscraper at 77 W. Wacker (right).
With the Seagram Building in New York (left), Mies van der Rohe took his tall, dark glass-box building and set it back on an open plaza, just like the Richard J. Daley Center in Chicago (right).
Dulles (top) in Virginia wasn’t just the first airport designed expressly for jets. Its weightless form and swoopy, expressive modernism influenced a wide range of buildings, including North Shore Congregation Israel in Glencoe (bottom).
Southdale Center (left) in Edina, Minn., was the country’s first fully enclosed, regional indoor shopping mall. With its interior courtyard and multiple levels of inward-facing stores, it created a formula duplicated at Schaumburg's Woodfield Mall (right)
