Jacqueline Susann was a 20th century author, who, by the 23rd century, was considered by Spock to be one of "the giants," along with Harold Robbins. Susann's writing contained profanity, reflecting the common usage of her era.
In 1986, the profanity featured in her collected works were cited by James T. Kirk as being reflective of typical speech when Spock noted Kirk's liberal use of such "colorful metaphors" upon arriving in that year. (Star Trek IV: The Voyage Home)
This character was only mentioned in dialogue.
Susann is best known for Valley of the Dolls, one of the best-selling works in publishing history.
