An exceptionally intelligent or precociously successful young person. The term is an alteration of Quiz Kids, a popular radio series of the 1940s that much later was revived on television. It involved a panel of five exceptionally bright children who were asked questions sent in by listeners. The current cliché was coined soon afterward and is no longer confined to children. The Economist had it in December 1962: “Critics . . . regard President Kennedy as a quiz kid surrounded by whiz kids.”
