Rogers Ernest Malcolm Whitaker (January 15, 1900 – May 11, 1981) was an editor of The New Yorker magazine who was known to readers for his many contributions to Talk of the Town under the pen name of E. M. Frimbo, World's Greatest Railroad Buff.
Whitaker lived in a theatrical boarding house down the hall from Mae West and worked at the New York Times checking bridal announcements for hoaxes placed by jilted suitors while also selling advertising for a trade magazine.
He accumulated 2.7 million miles of such travel during his lifetime, and wrote extensively about his trips under the pen name "E. M. Frimbo," often in collaboration with the staff writer Tony Hiss.
He put his knowledge of trains to good use during World War II, where he was commissioned as a Major in the U.S. Army's Traffic Control Division of the Transportation Corps.
In 1970, Whitaker testified before the Interstate Commerce Commission to argue against the Penn Central Railroad's plan to eliminate all 34 of its long-distance passenger trains.
