In the "Harry Potter" series, what is Headmaster Dumbledore's full name?

The story behind the answer

Albus Percival Wulfric Brian Dumbledore is Dumbledore’s full ceremonial name, given explicitly when he appears before the Wizengamot in Order of the Phoenix. The other options are fabricated and never appear in canon.

Rowling packs meaning into these names: Albus is Latin for “white” (light, purity); Percival is the Grail-seeking knight (wisdom and quest); Wulfric means “wolf-ruler” (strength); Brian adds a grounded, human touch; and Dumbledore is an old term for “bumblebee,” chosen because she imagined him humming. Memory tip: APWB—“A Powerful, Wise Boss”—Dumbledore. Or link each: Albus (light), Percival (quest), Wulfric (strength), Brian (human), Dumbledore (humming bee).
