During his 40-year tenure at SOM, Bruce Graham designed notable buildings all over the world from his home in Chicago, to Guatemala, Hong Kong, London, Cairo, and many other cities. He designed the
Willis Tower, tallest building in the world for nearly 36 years, the 100 story tall
John Hancock Center,
One Shell Plaza etc. He was extremely involved with the University of Pennsylvania, especially the School of Fine Arts. He believed that teachers of architecture should be currently involved in its practice. He was committed to the study of architectural theory and started the
SOM Foundation. He also taught an architectural studio at Harvard. Graham was a great collector of art. He befriended
Alexander Calder,
Joan Miró,
Chryssa and
