George Mouradian by profession is an engineer, yet also a history enthusiast. He is an American born Armenian who has researched Armenian history since his high school days, taught and was principal of Armenian Sunday School classes, lectured on Armenian and Genocide subjects, and has been very active in the Armenian community affairs. His job skills relate more to quality and reliability engineering than they do to history, but he has a love of the past and wanted to do something that could help others who are also interested. He has written several books on Armenian history and culture and on engineering, and has taught Reliability Engineering and Quality Management at the American University of Armenia. He wrote The Executioners because he wanted to tell the world about the Armenian Genocide and the avengers who tracked down the Ottoman Turkish culprits who killed the Armenians, Greeks, and other Christians. In addition, he wanted readers to learn about happened at Bank Ottoman, the Hamidiye Massacres of 1894-1896 and the founding of Operation Nemesis, the organization that formed to execute the perpetrators of the Armenian Genocide. George is also concerned with what is going on, in and among, Turkey, Armenia, and Azerbaijan today. The potential dynamics of the future are immense.
