John C. Portman Jr.

Portman also had a particularly large impact on the cityscape of his hometown of Atlanta, with the Peachtree Center complex serving as downtown's business and tourism anchor from the 1970s onward.

Portman's plans typically deal with primitives in the forms of symmetrical squares and circles.

Portman would develop a similar multiblock complex at San Francisco's Embarcadero Center (1970s), which unlike its Atlanta counterpart, heavily emphasized pedestrian activity at street level.

In 2009 Portman's work was featured in a major exhibition at Atlanta's High Museum of Art.

Also, he did, in fact, design buildings (like San Francisco's Embarcadero Center) that heavily emphasized pedestrian activity at street level.
