1939: Meeting of Pyry took place.....

On 25 & 26 July 1939, one of the most important events in the history of intelligence took place in the woods outside Warsaw. Just three weeks before the Government Code and Cypher School (GC&CS) moved to its War Station at Bletchley Park, its Head, Alastair Denniston, and its Chief Cryptanalyst, Dilly Knox, traveled to Warsaw to meet their Polish and French equivalents. During this meeting, Poland shared its successes against the ENIGMA with Britain and France. Poland’s main codebreakers were Jerzy Rozycki, Henryk Zygalski, and Marian Rejewski who joined the Polish General Staff's Cipher Bureau in Warsaw.

The first breakthroughs in regard to solving the Enigma did not occur at Bletchley Park, but rather had already occurred in Poland. German military messages enciphered on the Enigma were first broken by the Polish Cipher Bureau, beginning in December 1932. Three Polish mathematicians pioneered the solutions - Jerzy Rozycki, Henryk Zygalski and Marian Rejewski. The Poles had understood that it was necessary to use mathematics to look for patterns, and they had then taken a further step by building electro-mechanical machines to search for solutions, known as "bombas."

The GCHQ Departmental Historian said, “To the surprise of the British, the Poles, who had treated Enigma as a mathematical problem from the outset, were much further forward than they were both in terms of successful cryptanalysis and of building machinery to support cryptanalysis. The Poles were generous and shared everything they had with their allies.”

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.
