Who is John E. Marston?

Question

like, what does he do as a PR and what has he done?

Answer 1

From the first source below: "JOHN MARSTON defined a four-step management process for public relations in his 1963 book, The Nature of Public Relations. He used the acronym RACE (research, action, communication, evaluation). Since then many have used the acronym ROPE (research, objectives, programming, evaluation)."

The book is searchable in Google Book Search (second source below), but only available in snippet view; you can't really read it online.
