Background . Remus John Lupin was turned into a werewolf when he was young by Fenrir Greyback . In school he befriended James Potter , Sirius Black , and Peter Pettigrew . They were known for being troublemakers . Lupin tried to hide the fact that he was a werewolf from them , but they realized the pattern in his disappearances and studied to become animaguses ( wizards that can turn into animals at will ) to be with him . A young Severus Snape also discovered Lupin ' s secret when Sirius sent him to Lupin on a Full Moon , but he was rescued by James . During the first Wizarding War , Lupin was a member of the original Order of the Phoenix . In ' s third year he was hired as a Defense Against the Dark Arts teacher at Hogwarts School . He was popular amongst most of the students as he was more adept for teaching than his predecessors , Quirinus Quirrell and Gilderoy Lockhart . He taught the students about Boggart s , Grindylow s , and other magical creatures in addition to private lessons with Harry about Dementor s . During the same year , Sirius escaped from Azkaban because he was convicted for the murders of Peter Pettigrew and several muggles . Lupin struggled with whether or not to share this information with Dumbledore , but instead kept it to himself and conducted his own investigation , eventually discovering that Sirius was innocent and that Peter , who had been disguised as Ron Weasley ' s pet rat Scabbers had survived was to blame for the deaths . He joined Sirius in the Shrieking Shack when Sirius abducted Ron ( and Scabbers who was with him ) . He tried to calm down Harry and Hermione and convince them that he was still on their side . Snape also entered the scene shortly thereafter intent on rescuing the trio , but Harry knocked him out to listen to Lupin and Sirius ' explanation uninterrupted . They revealed that Scabbers was in fact a disguised Peter Pettigrew and , as per Harry ' s decision , planned to take him back to the school to clear Sirius ' name . However , Peter escaped in the chaos when Lupin transformed into a werewolf and Sirius took his dog form to keep him from hurting Harry , Ron , and Hermione . Lupin left the school shortly after Snape " accidentally " let it slip that he was a werewolf . Lupin was a later member of the reformed Order of the Phoenix , and married Nymphadora Tonks who had he had a child with , Ted . He fought in the Battle of the Department of Mysteries , the Battle of the Astronomy Tower , and finally in the Battle of Hogwarts where he was killed by Antonin Dolohov and Tonks was murdered by Bellatrix Lestrange .
