Professor Albus Percival Wulfric Brian Dumbledore, O.M. (First Class), Grand Sorc., D. Wiz., X.J. (sorc.), S. of Mag.Q. (c. Summer 1881 – 30 June, 1997) was an English half-blood wizard, who was the Defence Against the Dark Arts Professor, later the Transfiguration Professor, and later Headmaster of Hogwarts School of Witchcraft and Wizardry. Professor Dumbledore also served as Supreme Mugwump of the International Confederation of Wizards (?–1995) and Chief Warlock of the Wizengamot (?–1995; 1996–1997). He was a half-blood, Muggle-supporting wizard considered to have been the greatest wizard of modern times, perhaps of all time. The son of Percival and Kendra Dumbledore, and the elder brother of Aberforth and Ariana. His father died in Azkaban when Dumbledore was young, while his mother and sister were later accidentally killed. His early losses greatly affected him early on, even at his death, but, in turn, made him a better person.
