Just as real-life criminals seem to be less exciting than their fictional
counterparts, so cryptology seems to have been used far less in life than
in the pages of detective fiction. Indeed, the only major use of codes and
ciphers by criminals came during the American Prohibition era in the
1920s and early 1930s. The bootleggers' attempts to smuggle liquor past
American law-enforcement agencies required coordinating the
movements of ocean-going vessels with the small speedboats that would
bring the cases of bottles ashore. For this they used radio, and they
coded their messages. But many succumbed to the brilliant analyses of
Mrs. Elizebeth S. Friedman, wife of William F. Friedman, who served as a
cryptanalyst for the Coast Guard, helping it to keep out the smugglers.
As a result of the information obtained from crypt-analysis and from
direction-finding, the Coast Guard put increasing pressure on the
smugglers' activities
