Excerpt from army.mil:

In 1921, the Army's Chief Signal Officer offered Friedman a trial six-month government contract as a civilian cryptographer. This began William Friedman's 34-year career as an Army employee. By the end of 1921 he was named the Cryptanalyst of the Signal Service, accepting a salary of $4,500 per year. His duties ranged from teaching a course on military codes and ciphers, to writing the Army's first training manual on the topic, called Elements of Cryptanalysis. Friedman published numerous other works throughout the 1920s.
