Professor Quirinus Quirrell (26 September 1967 or earlier – 4 June 1992) was a half-blood wizard who attended Hogwarts School of Witchcraft and Wizardry and was Sorted into Ravenclaw House. He was the Muggle Studies professor at Hogwarts, though he later became the Defence Against the Dark Arts professor during the 1991–1992 school year. Before teaching Defence Against the Dark Arts, Quirrell went out in search of Voldemort, believing he could achieve recognition for finding him and could learn things that would ensure that no one laughed at him again. However, Voldemort, after finding out that he taught at Hogwarts, took over his body, subsequently turning him into a temporary Horcrux, though Quirrell put up some feeble resistance. He died in vain while trying to murder Harry Potter in the Underground Chambers.
