Nazi cipher machine designed to replace Enigma

STORY: This cipher machine was used by Nazi Germany's military

to encrypt strategic messages during World War Two

Location: Munich

The Cipher Machine 41 (SG-41) was invented by Fritz Menzer

It was designed to replace the Enigma machine

after it was cracked by Alan Turing and his team

[Carola Dahlke, Deutsches Museum cryptology curator]

"Fritz Menzer did not just come up with this machine - he developed other machines. And he also worked on cryptanalysis machines to crack the codes of other countries. There has been no research on that whatsoever. And that is what we are so excited about. We can talk about German cryptography today to explain the whole context."
