Gilderoy Lockhart (Order of Merlin, Third-Class) was once a DADA teacher at Hogwarts and he 'wrote' books about 'his' adventures. He erased memories of witches and wizards to make them his books so technically he's a fraud. Also many girls loved him even 11 year olds even though he's old. Gilderoy has a pimple on his face and handsome blonde hair.
