I'm ashamed to admit that I've completely missed the work of Stephen Potter as well as this article where Joseph Epstein gives a look . An excerpt:
Stephen Potter's own description of his career before writing his -manship books runs: "Failed academic lecturer, failed novelist, failed literary biographer, reasonable compiler [of anthologies], reasonable educational pamphleteer, failed editor, failed book critic, failed rowing blue . . ." He also wrote a play, which, he reports, "got as far as a read-through by a Sunday Society and is perhaps the only play which died on the first rehearsal."
