Edward Durell Stone (1902-1978)
The Aon Center (1972)
200 E. Randolph Street, Chicago
Originally the Standard Oil Building and later the Amoco Building, the Aon Center – at 83 floors – is Chicago’s third tallest building. Stylistically, it reflects the Classically-inspired Modernism that East Coast architects like Durell Stone and Philip Johnson embraced in the 1960s and 70s. Structurally, however, the building is pure Chicago, being a framed tube, a structural method first introduced in Chicago in the early 1960s and characterized by close-set perimeter columns tied together with spandrel beams that allow for column-free floorplans. (Framed tubes were the precursor to the bundled tubes used for the Sears Tower and other super tall structures.) Originally clad in thin slabs of gleaming white Carrara marble that eventually buckled and cracked, the building was re-clad in granite in the early 1990s.
New Graduate Residence Hall (1962)
1307 E. 60th Street, Chicago
Formerly known as the Center for Continuing Education, the New Graduate Residence Hall at the University of Chicago is characterized by its concrete pillars and horizontal massing. The facility features a bright and open center atrium and public spaces throughout for residents to use for study, community social activities, and small gatherings (adapted from the University of Chicago website).
