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.

Dorothy T. Blum

2004 Hall of Honor Inductee

Women in American Cryptology Honoree

Dorothy Toplitzky Blum significantly changed the way NSA did cryptanalysis. She was a pioneer in the use of computers to manipulate and process data automatically. As a manager, she showed empathy for her subordinates and worked to enhance the careers of everyone in her organization. Those who recall Dottie Blum usually rate her interest in people even higher than her technical gifts.

Ms. Blum was born in New York City in 1924. After earning a bachelor's degree from Brooklyn College, she joined the Army's cryptologic organization in 1944. After World War II, she moved to the Armed Forces Security Agency and later to NSA.

In the 1950s, Ms. Blum's professional interests had expanded from traditional cryptanalysis into cryptanalytic applications of computer technology to NSA's mission. She was a member of the Agency organization tasked to "keep abreast of the latest advances in the field of computing."

Ms. Blum was one of the pioneers in writing computer software at NSA. She led the effort to recruit Agency employees to learn how to program cryptanalytic techniques. She was aware of and taking advantage of the computer language FORTRAN at least three years before it became publicly available in 1957.

For the rest of her career at NSA, Ms. Blum significantly shaped the architecture of computer systems and automation of processes at the Agency. She was appointed chief of the Computer Operations Organization in 1972; at that time she was the only woman in the entire CO management chain. From 1977 until her death in 1980, she was Chief of Plans and Project Development in the Telecommunications and Computer Services Organization.

Dorothy Blum was also a leader in the WIN organization, at the time called Women In NSA. In 1983, WIN established the Dorothy T. Blum Award for excellence in employee personal and professional development.

Throughout her years in management, Ms. Blum was well known for her "sincere, personal interest in people and … for the astute and effective career guidance and counseling she gave many Agency employees."
