STORY: This cipher machine was used by Nazi Germany's military
to encrypt strategic messages during World War Two
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."
