The National Security Agency/Central Security Service Cryptologic Memorial exhibit is a replica of the black granite wall found in the NSA Headquarters building at Ft. Meade, MD. It is intended to honor and remember those who have given their lives, "serving in silence," in the line of duty since 1950. The Memorial was built in 1995 and lists the names of those cryptologists, military and civilian, who have made the ultimate sacrifice. The Memorial Wall was designed by an NSA employee and is 12 feet wide and eight feet high, centered with a triangle. The words "They Served in Silence," etched into the polished stone at the cap of the triangle, recognize that cryptologic service has always been a silent service — secretive by its very nature. Below these words, the NSA seal and the names of 177 military and civilian cryptologists (as of 01/19) who have given their lives in service to their country are engraved in the granite. The names are at the base of the triangle because these cryptologists and their ideals — dedication to mission, dedication to workmate, and dedication to country — form the foundation for cryptologic service.
