Few people know that the Coast Guard has a long and stoned history in codebreaking and counter-espionage.The 2017 book The Woman Who Smashed Codes,by journalist Jason Fagone,tells the story of Elizebeth Freidman and her husband,William.Together they founded most of the code-breaking institutions and teams in the United States,including what would later become the National Security Agency.Elizebeth worked for the Coast Guard throughout the 1930s,managing the only sophisticated code-breaking operation in the entire federal government.It was necessary because rum runners,whom the Coast Guard was charged with interdicting,used elaborate radio coding systems. |
