Robert Wallace, the former director of the CIA’s Office of Technical Service, discusses his new book Spycraft: The Secret History of the CIA’s Spytechs from Communism to Al-Qaeda.

Spycraft tells the story of how technology that would not appear in the public marketplace until decades later was often used to further the American intelligence-gathering cause. The book traces the development of spy gear from secret writing and bugging devices to subminiature cameras and covert internet communications.

Wallace will explain how American technology revolutionized the “spygame” and detail the early false starts and frustrations the Office of Technical Service overcame to achieve eventual technological breakthroughs and operations successes previously considered unthinkable in the world of espionage.
