1917: William Friedman & Elizebeth Smith married.

21 May 1917: William F. Friedman and Elizebeth Smith were married. This cryptologic power couple is well known for their significant pioneering contributions in the field of cryptology. Elizebeth S. Friedman is often referred to as (North) America's first female cryptanalyst. It was Elizebeth who introduced her husband to the field of cryptology. Although neither planned on a career in codebreaking, there were few ciphers that were indecipherable for the couple. William Friedman went on to be recognized as the greatest maker and breaker of secret messages. Much of what is done today at NSA can be traced to William Friedman's pioneering efforts.

On 30 October 1992, the NSA's Center for Cryptologic History published, "The Friedman Legacy: A Tribute to William and Elizebeth Friedman" which includes transcripts of the famed "Friedman Lectures." To listen to the audio collection or view transcripts, click the link below.

The George C. Marshall Foundation opened an exhibit, "Partners in Code: William and Elizebeth Friedman" in April 2015 as part of their Legacy Series: Codebreaking.

On This Day In History


  • 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.
