Biography

Calder Walton is Assistant Director of the Belfer Center's Applied History Project. Calder's research is broadly concerned with intelligence history, grand strategy, and international relations. His research has a particular focus on policy-relevant historical lessons for governments and intelligence communities today.

Calder is currently undertaking two major research projects: he is general editor of the multi-volume Cambridge History of Espionage and Intelligence to be published by Cambridge University Press. Over three volumes, with ninety chapters by leading scholars, this project will be a landmark study of intelligence, exploring its use and abuse in statecraft and warfare from the ancient world to the present day.

Secondly, Calder is finishing a book, Spies: the Long Cold War. British, American and Russian intelligence, about the long, and ensuing, intelligence struggle between Russia and the West. His research, and commentary, about espionage and national security frequently appear in major news and broadcast outlets on both sides of the Atlantic.

Calder's research builds on his first (award-winning) book, Empire of Secrets. British Intelligence, the Cold War and the Twilight of Empire (Harper-Press 2013). While pursuing a Ph.D. in History at Trinity College, Cambridge, England, and then a Junior Research Fellowship also at Cambridge University, Calder was a lead researcher on Professor Christopher Andrew's unprecedented official history of the British Security Service (MI5), Defend the Realm (2009). This research position gave Calder, for six years, privileged access to the archives of MI5, the world's longest-running security intelligence agency. As well as his research on intelligence history, Calder is also an English-qualified Barrister (attorney), and, among other matters, has worked on high-profile litigation and international arbitration cases involving government and national security issues and regulatory investigations. He lives in Cambridge, Massachusetts, with his partner and young son, who teaches him more about skulduggery than anything else.
