Who is credited as the fictional author of Hogwarts textbook Quidditch Through the Ages?

Kennilworthy Whisp is credited as the fictional author of the Hogwarts textbook Quidditch Through the Ages.

J.K. Rowling published Quidditch Through the Ages in 2001 as one of two charity companion books connected with Harry Potter. Inside the fictional world, it is presented as a history of the wizarding sport of Quidditch written by Whisp. The book covers the sport’s origins, rules, equipment, teams, and historical development.

The companion volume is designed to resemble a library book borrowed by Harry from Hogwarts. Rowling uses the fictional author and editorial notes to make the book feel like an artefact from the wizarding world rather than a standard narrative novel.

Readers sometimes confuse Whisp with Newt Scamander, the fictional author of Fantastic Beasts and Where to Find Them. They are different characters associated with different Hogwarts textbooks. The profits from the original books supported Comic Relief.
