Hogwarts School of Witchcraft and Wizardry

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].


Sometime prior to 1991, 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 skillsEdit


  • "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 scenesEdit

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


Notes and referencesEdit

  1. 1.0 1.1 In interviews, J.K. Rowling has stated that "all the portraits you see in the headmaster's study are all headmasters and mistresses who died". He must have been born prior to 1991 if he died before then.
