Hebern Electric Code Machine

National Cryptologic Museum

The National Cryptologic Museum is in the former Colony Seven Motel, a very unassuming building within sight of the National Security Agency headquarters at Fort George C. Meade, Maryland. Opened in 1993, it is filled with exhibits tracing the history of code making, code breaking, and code analysis. Outside are three aircraft representing aircraft used for “signals intelligence.”

Hebern Electric Code Machine
Hebern Electric Code machine, built around 1918, was one of the first U.S. developed modern coding devices, with one rotor and nicely detailed brass segments. Like the Apple, it was Made in California, USA.
M-9 Bombe Checking Machine
The M-9 Bombe Checking Machine was a U.S. device built in large numbers to perform brute force attacks on German codes during World War II. Several machines were fed the same code to find the proper rotor settings, and once found, the code could be translated.
Lorenz SZ42 "Tunny" code machine
The German SZ42 Schlüsselzusatz, or cipher attachment, was developed by the Germans in 1942 for use by the German Army. The British nicknamed it “Tunny,” after a type of tuna. This seemingly random name was due to the requirement to call all German encrypted traffic “fish,” as a security measure, which combined with British wit, made this “Tunny.”
Enigma machine, in public use
This Enigma machine and many variants were used by German forces throughout World War II. This particular device is used by visitors to create their own secret messages.
Thinking Machines CM-5
This Connection Machine CM-5 was built by the Thinking Machines Corp. It was used by NSA from 1991 to 1997, and was called “Frostburg,” after a college town in western Maryland. The many blinking lights are decorative.
IMZ-Ural motorcycle
This Soviet made IMZ-Ural motorcycle is a Soviet copy of a German BMW R-71 motorcycle from 1941. It was captured from the North Vietnamese Army by the U.S. during the Vietnam War, and has not a thing to do with cryptanalysis.
Rosetta Stone
Outside the National Cryptologic Museum gift store is this replica of the Rosetta Stone. Created around 196 BC, the Rosetta Stone displays a decree from an Egyptian king, written in Egyptian hieroglyphs, Demotic script and ancient Greek. Discovered by a French soldier during France’s invasion of Egypt in 1799, it provided the key to unlocking Egyptian hieroglyphs, much as modern code breakers look for keys in breaking coded texts. The real Rosetta Stone is on display at the British Museum in London. During their invasion, Napoleon’s troops also used cannon to blow off the nose of the Sphinx.
