Professor[2] Quentin Trimble[3] was a wizard who once occupied the post of Headmaster of Hogwarts School of Witchcraft and Wizardry[2]. He authored the textbook The Dark Forces: A Guide to Self-Protection, a required reading for any student enrolled in Defence Against the Dark Arts class[4].



Quentin attended Hogwarts School of Witchcraft and Wizardry in his youth, and was later appointed to the position of Headmaster of the school[2]. Sometime throughout his adulthood, Quentin (or, as he was known after his appointment as Headmaster, Professor Trimble) authored the book The Dark Forces: A Guide to Self-Protection, a required reading for any Defence Against the Dark Arts student[3][4].

Professor Trimble's portrait in the Headmaster's office

Sometime in or prior to the 1990s, Professor Trimble passed away, and a portrait was hung of him at the Headmaster's office in Hogwarts Castle so that he could offer advice and solace to future Headmasters of the school.[2] Unfortunately, whoever painted his name misspelled it, a mistake that was never fixed.[4]

Magical abilities and skills


  • "Trimble" is most likely a derivation of "tremble", meaning "to shake" - fitting considering his career as an author of books against the dark forces.

Behind the scenes

  • Professor Trimble's name is misspelt "Quintin Trimble" on his portrait in the films[4].


Notes and references

  1. J. K. Rowling stated at the Edinburgh Book Festival on 15 August 2014 (source) that all portraits at Hogwarts School of Witchcraft and Wizardry are of deceased individuals. Thus, Trimble must have died sometime in or before 1990s, given his portrait's appearance at Hogwarts in at least one of the Harry Potter films.
