1917: Zimmermann Telegram released to U.S. press.

1 March 1917: The Zimmermann Telegram was released to the U.S. press.

In January of 1917, British cryptographers deciphered a telegram from German Foreign Minister Arthur Zimmermann to the German Minister to Mexico, von Eckhardt, offering United States territory to Mexico in return for joining the German cause. This message helped draw the United States into the war and thus changed the course of history. The telegram had such an impact on American opinion that, according to David Kahn, author of The Codebreakers, "No other single cryptanalysis has had such enormous consequences." It is his opinion that "never before or since has so much turned upon the solution of a secret message."

In an effort to protect their intelligence from detection and to capitalize on growing anti-German sentiment in the United States, the British waited until February 24 to present the telegram to Woodrow Wilson. The American press published news of the telegram on March 1. On April 6, 1917, the United States Congress formally declared war on Germany and its allies.

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.
