Introduction
Editor’s Note: These brief sketches convey some sense of the pace and preoccupations of 15 Directors of Central Intelligence (DCIs) in their first 100 days. No regular cycles or predictive patterns emerge; some DCIs eased into their jobs, while others found themselves suddenly reacting to wars, scandals, or investigations. Nevertheless, DCIs Smith, McCone, Schlesinger, Colby, and Gates managed major changes in CIA’s structure and mission in their initial 100-day spans.
