1908: American cryptologic pioneer Frank Rowlett was born.

2 May 1908: American cryptologic pioneer Frank B. Rowlett was born. He was inducted into the NSA Cryptologic Hall of Honor in 1999 (see link below). Because of his importance in the protection of American communications, the Information Assurance organization has named its highest award the Frank Byron Rowlett Award.

From the Emory & Henry College Web site:

Born at Rose Hill in Lee County, Virginia, Frank Rowlett graduated from Emory & Henry College in June 1929 with majors in mathematics and chemistry and the Byars Medal in Science. In April 1930, he became the first junior cryptanalyst in the U.S. Army Signal Intelligence Service in the War Department in Washington, D.C. Eventually, he led a War Department group in writing ciphers for the U.S. Army, and breaking foreign code systems–notably Japanese codes.

Rowlett’s group solved the first Japanese system for encrypting diplomatic communications, which they called Red. In 1940, in a step ultimately critical to American and Allied victory in World War II, Rowlett’s group solved the more complex and sophisticated Japanese code they named Purple. Unaware their code had been broken the Japanese used Purple throughout the War, enabling American and Allied leaders to know important Japanese and German secrets by reading all messages passed between Tokyo and Berlin.

Working with the U.S. Navy, Rowlett designed communications codes that German, Japanese, and Italian code breakers never solved. Rowlett’s work saved the lives of thousands of American and Allied soldiers. Honored by President Johnson and by the U.S. Congress, Rowlett retired from federal service in 1966 as a founding father of the National Security Agency, which created a distinguished achievement award in his honor and named the Agency's academic center for training cryptanalysts Frank B. Rowlett Hall.

  • 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.
