Substitute professor of Care of Magical Creatures
(before 1994 - ?)



"I hope she stays, that woman! That's more what I thought Care of Magical Creatures would be like... proper creatures like unicorns, not monsters..."
Parvati Patil, after Grubbly-Plank's first lesson[src]

Professor Wilhelmina Grubbly-Plank was a substitute Care of Magical Creatures teacher. She was a witch with close-cropped grey hair and a very prominent chin. She was first met by Harry Potter's batch in 1994, taking over lessons when Professor Rubeus Hagrid was unable to teach. She taught the class again in part of the next school year when Hagrid was away on a mission for Albus Dumbledore.

Harry trusted her enough to ask her to heal his owl Hedwig when she was injured in 1995. She was brusque in her replies to inquires of Hagrid's whereabouts.


Early lifeEdit

Wilhelmina Grubbly-Plank was born, given to her elderly appearance, quite a long time ago, exact date is unknown. She presumably sat for O.W.L.s and N.E.W.T.s in her youth, in order to have her current job, and likely achieved a high grade in Care of Magical Creatures.

Hogwarts substitute teacherEdit



Professor Grubbly-Plank took over Rubeus Hagrid's lessons during January 1995, because Hagrid was indisposed after the defamatory article about him written by Rita Skeeter. She taught the students about Unicorns. When Hagrid resumed teaching in early February, Grubbly-Plank was no longer required and she left.


As Hagrid was absent in the beginning of the next school year, Grubbly-Plank was temporarily put in charge of Care of Magical Creatures again. She led the first years across the Lake on the enchanted boats, which was usually Hagrid's responsibility.

When Hedwig was hurt when returning from London on 7 October 1995, Harry asked Grubbly-Plank to heal her, which she did without much difficulty. Grubbly-Plank passed Dolores Umbridge's (then-High Inquisitor of Hogwarts) inspection without incident while she taught her students about Bowtruckles and gave out a homework assignments, to sketch and label

a drawing of one. After Hagrid's return on the 7 November, Grubbly-Plank was relieved of her duties again. When Hagrid planned to leave Hogwarts at the end of this school year, he implied that Grubbly-Plank would take on the class full-time. When he ran away from Umbridge and the Aurors, it is unknown whether she returned to teach Care of Magical Creatures for the remainder of that school year.

Personality and traitsEdit


Wilhelmina Grubbly-Plank is a very competent teacher, passing even Dolores Umbridge's inspection without incident (though Umbridge was disappointed by her expressing approval of Dumbledore). She seems always level-headed, cheerful and efficient, and claims to be very happy with the way Dumbledore runs the school. Many of the students, Gryffindors included, feel Professor Grubbly-Plank is a somewhat better teacher than Hagrid. Harry, Ron and Hermione do not admit this, however, simply because of their close friendship with Hagrid. Professor Grubbly-Plank also seems to have a bit of respect for Hagrid as she is never seen criticising his teaching skills and complimented his training of the school Thestrals. She is also known to smoke a pipe.
