description Arthur Scherbius Overview

Arthur Scherbius was a German electrical engineer and inventor associated with the Enigma cipher machine. He patented a rotor-based electromechanical encryption system in 1918, and the Enigma name later became associated with machines used by German military and government organizations, including Nazi Germany during the Second World War. Scherbius died before the wartime cryptanalytic history of Enigma was completed. He is chiefly relevant to the history of cryptography, electrical engineering, and twentieth-century communications security.

help Arthur Scherbius FAQ

What did Arthur Scherbius invent?

Arthur Scherbius patented a rotor-based electromechanical encryption system in 1918. His work led to the commercial Enigma cipher machine.

Was Arthur Scherbius the person who created the German military Enigma system?

Scherbius developed and patented the underlying machine, but later manufacturers and military organizations adapted Enigma for government and military use. The German military versions were more specialized than the original commercial machines.

How did the Enigma machine encrypt a message?

The machine used rotating electrical rotors to change the letter substitution as each key was pressed. That changing substitution made it much more complex than a fixed Caesar-style cipher.

When did Scherbius's encryption technology first become associated with Enigma?

The key patent dates to 1918, and commercial Enigma machines appeared in the 1920s. The name later became strongly associated with German military and government encryption.
