General History
The creator of the Enigma Cypher and Machine was of what nationality?
Answer
German
Explanation
German is correct: the Enigma cipher machine was invented by German engineer Arthur Scherbius, who patented it in 1918 and commercialized it in the 1920s. Germany’s military later adopted it widely during World War II.
Enigma used rotating rotors and a plugboard to create constantly changing letter substitutions, making messages seem unbreakable. Polish mathematicians first cracked key aspects in the 1930s and shared their breakthroughs with Britain, where Bletchley Park (Alan Turing, Gordon Welchman, and others) built Bombes to read German traffic. Memory tip: “Built in Germany, broken by Poles and Brits.”
