My wife’s great-great-aunt is the late Agnes Meyer Driscoll, a renowned cryptanalyst who played a central role in deciphering Japanese and German Navy codes in the 1920s and 30s.
Known as Madame X, she co-developed the “Communications Machine”, which became a standard enciphering device for the Navy for most of the 1920s, and was later considered the “first lady of naval cryptology”.
We were gifted some of her restricted-access Navy crypto assignments from the 1930s.
