Have you ever used Morse Code, written a hidden message in a note to a friend, or even spoken pig latin to keep a secret from some young kids?

Oftentimes computers are needed to “hack” into or break through these extra measures. But how was this done before computers? Join us as we take a breath of dead air with William and Elizebeth Friedman, who broke codes in the service of their country long before the digital age.SourcesClark, Ronald.
