Cryptologic Hall of Honor

The Cryptologic Hall of Honor was created in 1999 to pay special tribute to the pioneers and heroes who rendered distinguished service to American cryptology.

The standards are high for induction into this great hall. The individuals honored were innovators over their entire careers or made major contributions to the structure and processes of American cryptology. The men and women who have been inducted to the Cryptologic Hall of Honor are all greats in the once silent world of cryptology.

In the early days of America's cryptologic effort, many of the "giants" did both Signals Intelligence and Information Assurance. They made important contributions to both offensive and defensive cryptology. As such, they were among the first inducted into the Cryptologic Hall of Honor.

General Alfred M. Gray, USMC

2008 Hall of Honor Inductee


The outstanding reputation held by Marine Corps tactical signals intelligence (SIGINT) units today can be directly traced to the pioneering efforts and accomplishments of General Alfred M. Gray over four decades of distinguished service.

In his early career, General Gray built on the Marine Corps SIGINT experience of World War II and the Korean War to restructure USMC cryptologic operations and develop doctrines for SIGINT support to combat units. His early work and establishment of two units, one assigned to Europe and the other to the Pacific, formed the nucleus of what is known today as the Marine Cryptologic Support Battalion.

Through the 1960s, General Gray emphasized training for Marine Corps SIGINT personnel and the development of high foreign language proficiency. At USMC headquarters, General Gray oversaw the creation of concepts for direct support activities, and in 1962 commanded the first Marine Corps ground SIGINT unit to deploy to South Vietnam. He implemented and refined doctrine and practice for direct support to combat units in the war in Southeast Asia. In subsequent tours, he helped establish an all-source intelligence center that significantly enhanced intelligence and operational support to combat forces.

As he advanced to higher levels in the USMC, he continued to foster development of SIGINT capabilities strongly focused on direct support to the deployed forces. General Gray served as the 29th Commandant of the Corps. Marines in the Intelligence Community, appropriately recall General Gray as the "Cryptologic Warrior."
