The George C. Marshall Library in Lexington, VA, has a collection of documents left behind by codebreaking genius William Friedman. Today, I’m going to introduce a crypto puzzle I found there.
Codebreaker genius William Friedman needed 15 minutes to break this cryptogram. His wife Elizebeth, an outstanding cryptanalyst in her own right, needed 17 minutes. How fast can you solve it?
The gravestone of William and Elizebeth Friedman in Washington, DC, bears a hidden message. A few days ago I had the chance to go on site and take a look at it. Here’s my report, including a video that shows Elonka Dunin explaining the code.
Forget about all the Christmas carols! Here comes the Friedman’s musical cryptogram from 1933, as played by a scorewriter.
