Lockhart is obsessed with himself and his image. In his books, he tells of his exploits fighting various types of magical creatures, but the truth is that he simply interviewed the folks who really dealt with the creatures, then performed Memory Charms on them.
In June of 1993, while in the Chamber of Secrets, Lockhart accidentally blasted himself with the Memory Charm he was aiming at Ron and Harry. He lost his memory entirely as a result.
Lockhart is currently a resident of the Janus Thickey ward (ward 49, a closed, longterm ward for patients with permanent spell damage) at St. Mungo's Hospital, where he tends to wander off and get lost (OP23). Hospital ward-mates include Agnes (a fur-faced woman), Broderick Bode (now deceased), and Alice and Frank Longbottom, Neville's parents. He has recently mastered "joined-up" (cursive) writing. He gets fan mail all the time, although he has no idea why.

 Lockhart is the only character in the series to date to use a peacock-feather quill. The peacock is a traditional symbol of vanity, a very apt implication in Lockhart's case. His large, colourful wardrobe would also qualify him to be referred to as a "peacock" in the slang sense. (Peacocks also have other, more positive symbolism associated with them, but this is the most common modern English usage.) - MLW
