Larry Hancock brings his formal training in history and cultural anthropology to his research and writing on Cold War history and national security subjects. A graduate of the University of New Mexico, he earned his BA with honors, majoring in history, cultural anthropology and education. Following service in the United States Air Force, he pursued a career in technical education, computer/communications, and technology marketing. Larry then returned to his long-term interest in historical research. Known as a "document geek," he researched and published several collections of CIA, FBI, and military documents prior to beginning his writing efforts. His document work led to his becoming a board member of the Mary Ferrell Foundation, a major online interactive history archive. With over a dozen books in print, his works include an exploration of long term patterns in covert action and deniable warfare (Shadow Warfare and In Denial), the effectiveness of national command authority and command and control practices (Surprise Attack), and the political assassinations of the 1960s (Someone Would Have Talked, Killing King and The Awful Grace of God). His most recent book on the Kennedy assassination is Tipping Point: The conspiracy that murdered President John Kennedy.
