I thought I *knew*, as an evidence-based origins account and “official” answer, that the term flack for a public relations officer was closely tied to flak “anti-aircraft fire” — via the intermediate occupational descriptive term flak-catcher for their role in deflecting or absorbing abuse and accusation. And that this was popularized in Tom Wolfe’s essay title “Maumauing the Flack Catchers”. (His flak-catchers were local bureaucrats rather than p.r. agents but the idea was closely related.)

But I wanted to check with something besides my own memory, in scholarly sources or some easily-accessible online approximation thereto.

And so, how disappointing that Dictionary.com gives us a story about some guy named Flack, and no mention of flak except a link in a “words sometimes confused with flack” section.

  flack (n.)

“publicity or press agent,” in Variety headlines by September 1933; sometimes said to be from name of Gene Flack, a movie agent, but influenced later by flak. There was a Gene Flack who was an advertising executive in the U.S. during the 1940s, but he seems to have sold principally biscuits, not movies, and seems not to have been in Variety in the ’30s.
