Professor Neville Longbottom (b. 30 July, 1980) was a pure-blood wizard who began school at Hogwarts School of Witchcraft and Wizardry in 1991, and was sorted into Gryffindor house. His parents, Alice and Frank Longbottom, were well-respected Aurors and members of the first Order of the Phoenix. About sixteen months after Neville's birth, they were tortured to insanity by four Death Eaters with the Cruciatus Curse and placed in the Janus Thickey Ward at St Mungo's Hospital for Magical Maladies and Injuries, leaving Neville to be raised by his grandmother, Augusta Longbottom.

Throughout his school years, Neville was mostly a shy, clumsy, introverted boy who was constantly being told by his grandmother that he was not good enough or living up to his parents' accomplishments. However, in his later years, he showed that he possessed great courage and perseverance: he became an important member of Dumbledore's Army who fought in the Battle of the Department of Mysteries, the Battle of the Astronomy Tower, and the Battle of Hogwarts. During the Battle of Hogwarts, having refused Voldemort's invitation to join the Death Eaters, he destroyed the seventh and final Horcrux when he beheaded the snake Nagini. He also co-led the D.A. during his final year in opposition to the Death Eater professors. After the end of the Second Wizarding War, Neville briefly served as an Auror before becoming Hogwarts' professor of Herbology and marrying Hannah Abbott.
