Brian Gagwilde

"Artium Magister."

- Gagwilde's motto, as inscribed on the portrait depicting him and Professor Aragon playing chess.

Professor Brian Gagwilde was a wizard and a Headmaster of Hogwarts School of Witchcraft and Wizardry. Professor Gagwilde also wrote Jiggery Pokery and Hocus Pocus.

His portrait, in which he is depicted as playing a game of chess with Walter Aragon, is still at the Headmaster's office, to give advice to the current Head.
