1930: Solomon Kullback Reported to SIS to work for William Friedman.

22 April 1930: Solomon Kullback reported to SIS to work for William Friedman. He was inducted into the Cryptologic Hall of Honor in 1999 - see the excerpt below and learn more 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."

  • Birthday of cryptologic machine designer Edward Hebern. Hebern's five-rotor cipher machine is cryptologically significant as part of the overall evolution in U.S. manufactured rotor devices. The National Cryptologic Museum has two very rare five-rotor Hebern cipher machines in its collection.

About Us

The NCMF directly supports the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. We think you will agree it is truly a "museum like no other."

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a 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 NCMF acquires the best artifacts for the NCM and supports new educational and interactive exhibits.

The NCMF provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and innovation through valued awards, and hosts educational, cryptology-related exhibits at various community events.

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 NCMF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCMF and NCM share a joint three-fold mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
