Gilderoy Lockhart is a popular author and wizarding celebrity who has written many books about his adventures encountering dark creatures, and is the Defence Against the Dark Arts instructor for "Chamber of Secrets". He is unpopular with most of the staff, particularly Snape. He is greatly admired by many others, particularly women (including Hermione and the Weasley mother Molly Weasley) who find him attractive. Harry dislikes Lockhart for a number of reasons: his arrogance, his belief that Harry flew to Hogwarts in Mr. Weasley's car to seek further attention, his penchant for handing out signed photos of himself, and the trouble he has with simple magic such as healing Harry's broken arm (he accidentally vanishes of Harry's arm bones instead). Lockhart is exposed as a charlatan and a coward when he attempts to avoid entering the Chamber of Secrets by revealing to Harry and Ron that he never performed the amazing feats documented in his books, instead passing off the experiences of other witches and wizards as his own and erasing their memories to prevent them from revealing the truth. He attempts to cast a Memory Charm on Harry and Ron using Ron's damaged wand, but the spell backfires and leaves him with near-total amnesia.
