What does creativity have to do with winning the Cold War? In the late 1950s, the top architects of the day were invited to participate in a historic study of creativity at the Institute of Personality Assessment and Research at the University of California, Berkeley. Eero Saarinen, I.M. Pei, Philip Johnson, Louis Kahn, and dozens of other famous mid-century architects were tested in an effort to understand what makes a person creative. The story is now published for the first time in Pierluigi Serraino's The Creative Architect: Inside the Great Midcentury Personality Study.
