Bruce Graham (1925-2010) was a Colombian-born American architect who spent his career at the Chicago office of Skidmore, Owings & Merrill (SOM). He is best known for two of Chicago's most significant skyscrapers: the John Hancock Center and the Willis Tower, originally named the Sears Tower, which was the world's tallest building when completed. Graham's work helped define a structural expressionist approach to high-rise architecture. He also contributed to other major projects including the Inland Steel Building in Chicago.

How are the John Hancock Center and Willis Tower structurally different?

The John Hancock Center expresses a braced-tube system through the giant diagonal members visible on its exterior. Willis Tower instead uses nine square tubes bundled at different heights, producing its stepped silhouette.
