British scientist Alan Turing, leveraging on earlier breakthrough by three Polish military intelligence cryptanalysts Marian Rejewski, Jerzy Różycki and Henryk Zygalski, led the effort to break the cipher. Enigma machines were widely used by Nazi Germany during the World War 2.
ENIGMA MACHINE SERIES
The Enigma machines were a series of electromechanical rotor ciphers based on a German engineer, Arthur Scherbius's invention.

It was a combination of mechanical and electrical subsystems including a keyboard, rotating disks called rotors arranged adjacently along a spindle, and stepping components to turn the rotors when keys were pressed. The Enigma machine had been around since the early 1920s and is most closely associated with Nazi Germany. The principal cipher was “Heimisch” for U-boats and surface ships in home waters, including the Atlantic. Naval Enigma signals used different ciphers, each with its own daily key (rotor order, ring settings, plugboard connections, and ground setting).
ENIGMA MACHINE CODE
Breaking the naval code gave the British an advantage in the Battle of the Atlantic. The machine used by the German army was decrypted as early as 1932 by Polish cryptographers, who later passed their methodology along to the British and French.
