Gilderoy Lockhart was the Defence Against the Dark Arts teacher in Harry Potter's second year of schooling.
Professor Gilderoy Lockhart Order of Merlin - Third Class, was a wizard, a Ravenclaw student at Hogwarts School of Witchcraft and Wizardry, and later a famous wizarding celebrity who authored many books on dark creatures and his encounters with them. Prior to his tenure as Professor of Defence Against the Dark Arts at Hogwarts School of Witchcraft and Wizardry during the 1992–1993 school year, he received many prestigious awards, such as Order of Merlin, Third Class; Honorary Member of the Dark Force Defence League; and five-time winner of Witch Weekly's Most Charming Smile Award.
He never actually did any of the heroic acts he claimed to have done but instead used his considerable talent in Memory Charms to force the actual people who had done them into forgetting what they did. Ironically, Lockhart lost his memory on May 29, 1993 due to a backfired Memory Charm cast by Ron Weasley's damaged wand and he became a permanent resident of St Mungo's Hospital for Magical Maladies and Injuries. Following his hospitalisation, he dictated his final book entitled: Who Am I?
