Hogwart's School for Witchcraft and Wizardry
Nurse Poppy Pomfrey
Madam Poppy Pomfrey (b. 1950s or earlier) was the Matron and nurse in charge of the Hospital wing at Hogwarts School of Witchcraft and Wizardry and is depicted as a stern and professional woman who takes her chosen path quite seriously. She was apparently on cordial terms with Professor Minerva McGonagall, who calls her by her first name.
Pomfrey was already the school nurse when Harry’s parents were students, as she is mentioned as escorting Remus Lupin out to the Whomping Willow, the entrance to the Shrieking Shack, in order for him to transform. Severus Snape sees the two of them walking out on the school grounds, and decides to follow them, causing Sirius Black to play a near-fatal prank on Snape. Due to their knack at getting involved in things over their heads, Harry Potter and his friends ended up in Pomfrey’s care relatively often while they were students.
Poppy Pomfrey was born during or prior to the 1950s, and purchased her wand prior to her magical instruction, possibly at Hogwarts School of Witchcraft and Wizardry. Her success in her O.W.Ls and, possibly, N.E.W.Ts are unknown, though she presumably had a talent for healing spells and Potions.
Poppy Pomfrey (or known as Madam Pomfrey by students) started her career at Hogwarts School of Witchcraft and Wizardry as the school’s matron and nurse at a relatively young age. She is a well-respected staff member at Hogwarts and is good friends with fellow staff members Albus Dumbledore and Minerva McGonagall. By 1971, Albus Dumbledore trusted her to take on the task of caring for new student Remus Lupin, who was infected with lycanthropy due to the bite received from werewolf Fenrir Greyback, which turned him a werewolf on every full moon.
As his caretaker, Poppy would escort Lupin to the Whomping Willow and use its secret passage way into the Shrieking Shack, where he would be kept overnight to prevent any harm caused to the other students. She is dedicated to her job, hardly asking questions on how students got some of their injuries (despite how suspicious they may seem), but just concentrate on treating her patients and ensuring that they get ample rest after treatment.
