Albus Dumbledore

"*Albus Dumbledore was never proud or vain; he could find something to value in anyone, however apparently insignificant or wretched, and I believe that his early losses endowed him with great humanity and sympathy. I shall miss his friendship more than I can say, but my loss is as nothing compared to the Wizarding world’s. That he was the most inspiring and the best loved of all Hogwarts headmasters cannot be in question. He died as he lived: working always for the greater good and, to his last hour, as willing to stretch out a hand to a small boy with dragon pox as he was on the day that I met him.*"

— Albus Dumbledore's obituary by Elphias Doge
Professor Albus Percival Wulfric Brian Dumbledore, O.M. (First Class), was an English half-blood wizard, who was the Defence Against the Dark Arts Professor, later the Transfiguration Professor, and later the Headmaster of Hogwarts School of Witchcraft and Wizardry. Professor Dumbledore also served as Supreme Mugwump of the International Confederation of Wizards and Chief Warlock of the Wizengamot. He was a 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. While initially unable to directly act against Gellert Grindelwald, due to their past Blood pact, the Ministry's surveillance of him, his lingering feelings of love toward Grindelwald, and his lingering guilt over Ariana's death, Dumbledore sent Newt Scamander to New York to release the Thunderbird Frank, and later sent Newt to Paris to rescue Credence Barebone. After the tragic death of Leta Lestrange in Paris, Dumbledore became determined to contribute helpful advice to the resistance against Grindelwald, notably Newt, Theseus, Tina, Jacob, Yusuf, and Nagini in the Global wizarding war. Initially unbeknownst to Dumbledore however, Grindelwald intended to use the former's alleged Obscurial relative, Aurelius Dumbledore, as a weapon against him.

   Following the Global wizarding war and the end of the *For the Greater Good* revolution, regardless of Aurelius Dumbledore's fate, Dumbledore became most famous for defeating Grindelwald in arguably the most epic duel of all time. Dumbledore also gained much more recognition with his involvement in the discovery of the twelve uses of dragon's blood and his work on alchemy with Nicolas Flamel.

It was through Dumbledore that resistance to the rise of Lord Voldemort was formed. He founded and led the Order of the Phoenix against Voldemort during the First Wizarding War. Following Voldemort's sudden return and the start of the Second Wizarding War after the resignation of Cornelius Fudge, Dumbledore swiftly formed and lead the second Order of the Phoenix. He would also support Jacob's sibling in the latter's quest for the Cursed Vaults, and consistently aid the trio of Harry, Ron, and Hermione during their first six years at Hogwarts, thus leading them to name Dumbledore's Army after him.

Due to the fact that he had a keen mind and legendary power, Dumbledore became the only wizard that Voldemort ever feared. He was the wielder and the master of the Elder Wand from 1945 until 1997 and considered by many as the greatest Hogwarts Headmaster. As he was about to die by a cursed ring, Dumbledore planned his own death with Severus Snape. Per the plan, Dumbledore was killed by Snape during the Battle of the Astronomy Tower. Though he was no longer alive at the time, it was through Dumbledore's manipulations that Lord Voldemort was ultimately defeated, and lasting peace finally restored to the wizarding world. Dumbledore is the only Headmaster that was laid to rest at Hogwarts. A portrait of him still remains at Hogwarts. Harry Potter later named his second son Albus Severus Potter after him.
