Severus Snape significant person Albus Dumbledore
Severus Snape is a fictional character in J. K. Rowling's Harry Potter series. He is an exceptionally skilled wizard whose extremely cold and resentful exterior conceals deep emotions and anguish. A Professor at Hogwarts School of Witchcraft and Wizardry, Snape is hostile to Harry due to his resemblance to his father James Potter, who bullied Snape during their time together at Hogwarts.
As the series progresses, Snape's character becomes more layered and enigmatic. A central mystery is unravelled concerning his loyalties. Snape dies at the hands of Lord Voldemort in the seventh book, at which time his back story is revealed. Despite his attraction to the Dark Arts and Voldemort's ideology of wizard supremacy, Snape's love for Muggle-born Lily Evans, Harry's mother, eventually compelled him to defect from the Death Eaters. He then became a double agent for Albus Dumbledore and the Order of the Phoenix. The fact that Lily chose James Potter, Harry's father, only fuels Snape's hostility towards Harry.
Snape's character has been widely acclaimed by readers and critics. Rowling described him as "a gift of a character" whose story she had known since the first book. Elizabeth Hand of The Washington Post explained that Snape's life "is the most heartbreaking, surprising and satisfying of all of Rowling's achievements". Actor Alan Rickman portrayed Snape in all eight Harry Potter films, released between 2001 and 2011.Appearances
Harry Potter and the Philosopher's Stone
Snape first appears in Harry Potter and the Philosopher's Stone, shortly after Harry arrives at Hogwarts. He is the school's Potions Master, though he is widely rumoured to covet the Defence Against the Dark Arts post. Snape himself confirms the rumour in Harry Potter and the Order of the Phoenix. Snape is a sinister and malicious teacher who makes frequent snide and disparaging remarks at Harry's expense. He quickly becomes the primary antagonist of the book, as Harry suspects him of plotting to steal the Philosopher's Stone, and of attempting to kill him. Only the climax of the book reveals that Professor Quirrell, in league with Lord Voldemort, is the real enemy; Snape, suspicious of Quirrell, had been looking out for Harry throughout the book. In the final chapter, Dumbledore suggests that because Harry's father James had saved Snape's life when they were both students, even though the two detested each other, Snape felt responsible for Harry in return. As the final book reveals, this is not the full story. In any case, even after Quirrell's true role is revealed, Harry retains feelings of suspicion and resentment towards Snape, and their relationship remains tense. Snape's behaviour and attitude towards Harry also remain unchanged.Loyalties
Snape's true loyalty was one of the most significant questions in the series up until the end of the final instalment, Harry Potter and the Deathly Hallows. Although the first five novels depict him as unfair and vindictive towards Harry and his friends, he invariably ends up protecting or otherwise helping them when they or their allies are in danger. Several characters express doubts about his loyalty, but Dumbledore's trust in him is generally taken to be the final word. Curiously, the same thing appears to happen in the opposite side, when we see how Bellatrix Lestrange mistrust Snape and only the word of Voldemort seems to protect him from the suspicions of the other death-eaters. The sixth novel, Harry Potter and the Half-Blood Prince, departs from that model. In the second chapter, Snape claims to have been working for Voldemort ever since the latter's return, and only pretending to help Dumbledore. By killing Dumbledore toward the end of the novel, Snape seems to place himself firmly in Voldemort's camp. Rowling maintains this impression through the early chapters of the seventh novel. However, near the climax of the book, Snape leaves Harry his dying thoughts (to be viewed in the Pensieve) and ultimately reveals to Harry that he had been loyal to Albus Dumbledore throughout the series. Snape's fierce devotion to and love of his childhood friend Lily, Harry's mother, is the foundation of that loyalty.After Harry Potter and the Half-Blood Prince, Snape's loyalty was a matter of intense debate among the fans. The issue was given special attention in the marketing campaigns on behalf of the last book, Harry Potter and the Deathly Hallows. "Is Snape Good or Evil?" was one of the questions in Scholastic Inc.'s seven-question series, part of its marketing campaign for the book. As part of the Waldenbooks marketing campaign, two free stickers, one that said "Trust Snape" and another that stated "Snape Is A Very Bad Man" were available with the book. Borders Group published a separate book on the topic, The Great Snape Debate, containing essays and arguments from both sides of the debate.
