"The puzzlemaster was Paul Derthick, a longtime research analyst in NSA's Operations Organization"--Page 1.
"For the first few months, the "Headline puzzle--an NSA original" alternated issues with an interesting but exceptionally short crossword puzzle. By April of 1965, however, the Headliner Puzzle had become a monthly feature. In 1971 puzzle solvers were challenged not only to decipher the headlines, but to recover the setting word, keyword, and "hat" for the puzzle as a whole"--Page 1.
