Cafe Society

"Cafe Society" was coined by Cholly Knickerbocker (Maury Paul) at the New York American in 1919. There was a movie titled Cafe Society (1939). Lucius Beebe consulted on the movie and was sometimes given credit for the term, but Beebe gave credit to Paul.

The next morning (Feb. 1919? This reel is not in the NYPL when I looked - ed.), history, to coin a phrase, was made. For (Pg. 279 - ed.) Maury Paul had given this new order of things a name. The name was: "Cafe Society." In the years to come, that tag was to become more and more widely known; it was the title of a movie in which Madeleine Carroll played a headstrong debutante the way Hollywood heroines always play headstrong debutantes (with overtones of Jimmy Durante); it became the name of not one but two New York nightclubs (one of which first labeled itself "The Right Place to Meet the Wrong People," and had a ten-cent cover charge, but later degenerated into a standard cellar joint); it became the qualifying phrase for all murders involving anyone who wore a white collar, and it even turned up as the title of a directory unsuccessfully designed to supplant the Social Register and known as Cafe Society Register. It became, as we say, a household word, as accepted as Walter Winchell's "blessed event" or "renovated," and and as casually used as "glamor girl," also coined by Maury. It came into being simply because The Man sat in the Ritz one night and saw some Goelets sitting with a Widener and a Corrigan.

The popularity of the term, it must be admitted, is due in a great part to Lucius Beebe, who started using it often in writing his weekly pillar in the Herald Tribune on cooking, drinking and the best place to buy mauve garters. This was one instance where Mr. Beebe, ordinarily astute but never as shrewd as Maury by far, beat Mr. Paul to the draw. For when, in 1938, Paramount Picture set about making their epic called "Cafe Society," that organization paid $5,000 merely for the use of the title, but not to Maury Paul. They paid it to Lucius Beebe. This sent Maury into what amounted to a purple rage.

A familiar figure around town, he was never flamboyant in his dress and was conventionally retiring in manner. He called many of the town's social leaders by their first names. Mr. Paul invented the phrase "Cafe Society," to describe the night club and restaurant crowd, also coined the expression, "Old Guard," which included members of the old New York families, and even these he divided into two classes, A and B.
