Hebern Device

The machine was designed by Edward Hebern to encipher and decipher typed messages. It used several rotors with 26 letters to encrypt messaging similar to other World War II devices. Hebern designed the device through his company, Hebern Electric Code, but it was never used by the U.S. government due to weaknesses discovered by William F. Friedman.
