What pseudonym is used for the Nancy Drew series? Carolyn Keene is the house pseudonym used for the Nancy Drew Mystery Stories. It does not identify one single author: the books were produced by the Stratemeyer Syndicate, which planned series, commissioned manuscripts, and published them under a consistent fictional author name.

Mildred Wirt Benson wrote many of the earliest Nancy Drew books and is often credited as the principal creator of the character's original voice and adventurous personality. Other writers later contributed manuscripts, including Harriet Adams, the daughter of syndicate founder Edward Stratemeyer.

The syndicate's ghostwriters generally signed away authorship rights and were expected to keep their involvement confidential. Early writers were paid a flat fee rather than receiving royalties, which helped publishers maintain the illusion that Carolyn Keene was a single continuing writer.

Edward Stratemeyer is therefore not the pseudonym, although he founded the syndicate and originated the series concept. Franklin W. Dixon is another house name associated with the Hardy Boys, while Ann Granger is a real British mystery novelist.
