The wonderful Dumbledore is the benign and caring Headmaster of Hogwarts School of Witchcraft and Wizardry.  He hides an inner strength and is known to be the only Wizard that Voldemort was ever scared of.  He mentors Harry throughout his character is a wondrous one, although sometimes it's confusing and eccentric. He says so many brilliant things its hard to settle on a quote, but my favourite is 'Happiness can be found even in the darkest of times, when one only remembers to turn on the light.'
