Excerpted from the NSA article: "The American Revolution's One-Man National Security Agency"
James Lovell was the American Revolution's one-man National Security Agency, for he was the one and only cryptologic expert Congress had, and, it is claimed, he managed to decipher nearly all, if not all, of the British code messages obtained in one way or another by the Americans. Of course, the primary way in which enemy messages could be obtained in those days was to capture couriers, knock them out or knock them off, and take the messages from them. This was very rough stuff, compared to getting the material by radio intercept, as we do nowadays.
This one-man NSA was James Lovell, and besides being a self-trained cryptologist, he was also a member of the Continental Congress. With his cipher designs, Lovell became America's first cryptographic tutor.
