Welcome to the National Cryptologic Foundation. We strive to influence the cryptologic future by sharing our educational resources, stimulating new knowledge, and commemorating our heritage. The Foundation also provides needed support for the National Cryptologic Museum (NCM).

  • ...The nation’s brightest young minds to consider careers in STEM and cyber related fields

  • ...Robust dialog with the American public on cyber policy, technology, and privacy

  • ...Those who “served in silence” with valor and distinction, especially those who gave their lives in service

1994: Solomon Kullback Died

Thursday, August 5, 2021

5 August 1994: American cryptologic pioneer Dr. Solomon Kullback died. In the photo - Dr. Kullback is standing - second from left. William Friedman is seated, far right, and Frank Rowlett and Abraham Sinkov are standing first and second from the right.

The below excerpt is taken from NSA's Cryptologic Hall of Honor entry for Dr. Solomon Kullback, a 1999 Inductee more about Dr. Kullback's experience and accomplishments in the full entry via the link at the end of the page.

Dr. Solomon Kullback was one of the original three "junior cryptanalysts" hired by William Friedman to work for the U.S. Army's Signals Intelligence Service. For the better part of a decade, Kullback, together with William Friedman, Frank Rowlett, and Abraham Sinkov, constituted the Army's sole effort against the codes and ciphers of potential enemies, and the nucleus of the Army communications intelligence (COMINT) service thereafter.

The original members of SIS were a unique quartet, men who ought to be national heroes. Their love was as much for the process as the result, the cryptanalysis as the intelligence derived from it, but what they did, the breakthroughs against the high-level code and cipher systems of our principal enemies, surely shortened the period of war by many months and resulted in the saving of thousands of American and British lives.

Years later, in an interview with NSA's oral historian, Solomon Kullback was modest about his accomplishments, but made a telling comment about his activities against German cryptography. He still recalled many of the details of these systems, described them in considerable detail, and commented: "They were a lot of fun."

About Us

T he NCF's Vision is to Influence the cryptologic future by sharing our educational resources, stimulating new knowledge, and commemorating our heritage.

The NCF also provides needed support to the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community.

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a unique and priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCF acquires the best artifacts for the Museum and supports new educational and interactive exhibits.

The Foundation provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and cyber education and careers,  hosts educational, cryptology-related exhibits at various community events, and honors the people— past, present, and future—whose contributions to our national security protect and make possible our way of life.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCF has a three-part mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
