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.

Cryptologic Hall of Honor Nomination Process

The Cryptologic Hall of Honor is an important part of the NSA/CSS heritage program and pays tribute to those who made extraordinarily important contributions to America’s national security through cryptology, or who had a lifetime of high achievement in the cryptologic field. The nomination process is undertaken by a Panel supported by the Center for Cryptologic History (CCH) and adheres to professional historical standards for research, analysis, and objectivity.

The call for nominations for the Cryptologic Hall of Honor is issued annually, usually in February. However, they may be submitted at any time; the formal call is merely a reminder that the deadline for the current cycle is approaching. Nominations received after the deadline (usually in March) will be considered for the following year. Note: It is imperative that nominations adhere to the prescribed format and word count restrictions. Failure to do so requires reformatting and editing by CCH staff and may result in delayed consideration of a nominee and/or improper consideration of career accomplishments.

• The criterion for selection is high achievement using cryptology to preserve the security of the United States and the American people.
• This achievement could be in one major event or over a career.
• “Cryptology,” for the purposes of these nominations, is defined as any direct or enabling function that supports NSA mission success.
• Nominations may be for individuals or groups.
• While a majority of nominations have been U.S. government employees or members of the armed forces, any individual may be nominated and selected, including foreign partners, contractors or persons from academia, e.g.
• Nominees need not be deceased to be submitted, however, they must have departed full-time cryptologic service at least 10 years prior to their nomination.
• Nominations, once formally submitted, will remain active for ten years. If new information becomes available after that time, nominations can be re-submitted to the Sub-Panel.

The Panel Executive Secretary will compile the final selections into a staffing package and forward to the Director NSA for final approval. Upon the Director NSA’s approval, Strategic Communications will schedule a ceremony to induct the new Cryptologic Hall of Honor members in the Canine Suites (usually in October or November).

African Americans in Cryptologic History

The experience of African Americans at NSA and its predecessor organization mirrors the African American experience in the United States and the Federal Government in the latter half of the twentieth century.

The first African American hired by the Army Security Agency, and who later made the transition to the Armed Forces Security Agency, worked first in a segregated office. Senior supervisors were white and many of the duties were menial ones not wanted by whites.

In the 1950s, African Americans began to move into the mainstream workforce. The segregated office was abolished and more African Americans received supervisory positions.

Many African Americans advanced to NSA's senior ranks. Many of those who began their careers in the segregated work environment finished at the top of their profession.

For many years it was believed that African Americans had first been hired to work in cryptology only after World War II. Recent research has revealed, however, that the first large-scale hiring program for African Americans began in 1944. By the end of the war, a segregated office of thirty African Americans was engaged in researching messages encrypted in unknown systems, analyzing them, and producing translations.

Women in American Cryptology

Although the number of women involved in cryptology has always been lower than the number of men, they have not been completely absent from the field either. Women have always been involved in America's cryptologic history. Some have reached the higher ranks of management and a few have been considered the expert in their field.

Cryptologic pioneers, such as Elizebeth Friedman and Agnes Driscoll, are well known to those who study cryptology. Were it not for their early involvement, the women of today may not have been able to reach their current numbers or status. But not every woman, or their organizations, has made it into the history books. Thousands of lesser-known women cryptologists have also played a role in creating the legacy women enjoy today. Their achievements, and in some cases their escapades, furthered the progress of women in cryptology. Women's involvement was sometimes sporadic, but significant.

The Women in Cryptologic History exhibit at the National Cryptologic Museum highlights the contributions of twenty-four women who have helped create cryptologic history. The display begins with a member of the Culper Spy Ring during the American Revolution who used her laundry as a secret code. Women spies from the Civil War also used codes and ciphers to aid those fighting for the causes they believed in. But it wasn't until the twentieth century that women began to work full-time in cryptology. During WWI several women considered to be cryptologic pioneers began their careers, as did some women few people today would know. During WWII thousands of women joined the military or worked as civilians for the military as cryptanalysts, intercept operators, technicians, machinists and every other position available in cryptology. Many of those women chose to stay in the field after the war, providing breakthroughs and contributions throughout the Cold War. Eventually, women rose to the highest ranks of management and today continue to support, develop, and build the cryptologic legacy of tomorrow.
