The term egghead has mostly been retired to the Hall of Lost Insults, hung up alongside Poindexter and gomer in the “Making Fun of Nerds” section. But as Aaron Lecklider's surprising history Inventing the Egghead shows, the figure of the unworldly and fragile genius showed up across postwar popular culture, in comic pop songs, science fiction, television, and the theater. Lecklider demonstrates how the suddenly omnipresent and mockable egghead was a creature of its time, born of postwar anxieties over Communism, gender roles, and race.
