Charles Babbage KH FRS was born on this day in 1791; pretty much the
father of the computer, a model of his "difference engine" built to the
standards of the day worked, complete with its printer. What is not so
well known about him was that he dabbled in cryptography, and broke the
Vigenère cipher; unfortunately for him it was classified as a military
secret, so one Friedrich Kasiski got the credit instead.

Did 20th century pioneers such as von Neumann and Zuse know about Babbage?
