Albus Dumbledore
In conjunction with the release of the "Harry Potter and the Half-Blood Prince" film in 2009, the organization launched a "What Would Dumbledore Do" campaign, asking fans to tweet about the lessons they learned from Harry Potter's headmaster Albus Dumbledore using #dumbledore, attend the film release wearing a nametag with one thing Dumbledore taught them, and apply those lessons in their lives.
