Try your hand at encoding a message using an authentic, World War II-era German Enigma machine; learn about the challenges law enforcement faces in combating terrorism; and discover the reality of espionage within our borders. These topics will be examined by experts whose careers were devoted to spying and protecting America from spies as part of a lecture series organized by the Museum of Nature & Science and the World Affairs Council of Dallas/Fort Worth in conjunction with the museum’s exhibit, The Science of Spying.


Security threats today come not just from powerful rogue nations but also from individual terrorists with unprecedented access to weapons and information. Since 9/11, intelligence and security experts have placed a stronger emphasis on discovering their changing tactics and examining their different ideologies. Drawing on 30 years of experience with the FBI, Oliver "Buck" Revell will analyze terrorist acts of the past and discuss the challenges facing law enforcement in its response to future threats.


Revell ended his career at the FBI as associate deputy director, a position in which he oversaw all investigative, counterterrorism, counterintelligence and international programs. He took charge of a joint FBI/CIA operation, which led to the first overseas apprehension of a terrorist. After leaving the FBI, he served as president of the Law Enforcement Television Network before founding the Revell Group International, a network of former FBI, intelligence, and military senior officials who provide counsel for international businesses. Revell is chairman of Visiphor Corp. of Vancouver, Canada; senior advisor to Synfuels International of Dallas; a director of Vance Security USA, Inc., Oakton, Va.; and a trustee of the Center for American & International Law in Plano.
