Wilhelmina Grubbly-Plank background
We don’t know much about Wilhelmina’s past.
In fact, even the books never mentioned a thing about it.
However, we do know she was born sometime before 1990.
Because Wilhelmina was much older when we first saw her.
And that was in the year 1994.
Wilhelmina Grubbly-Plank occupation
Wilhelmina Grubbly-Plank was a substitute professor in Care of Magical Creatures. A course that introduced all the magical creatures in the wizarding world.
“Wait, didn’t Hogwarts have Hagrid?”
Well, of course they did.
But Rubeus Hagrid wasn’t always there.
For example, there was a time when he was sent away to Azkaban. A maximum-security prison.
As a result, someone had to fill in for his position.
And that’s where Professor Grubbly-Plank saved the day.
Plus, you don’t get a teaching position in Hogwarts without being smart.
So I’m sure the students were in pretty good hands as well.
Wilhelmina Grubbly-Plank character
Professor Wilhelmina had short grey hair.
Plus, she also had a pointed chin too.
She liked wearing a dark burgundy witch hat.
And she matched it with a brown undershirt…
With a lighter brown wizard robe to complete the look.
As for her personality, Wilhelmina was very cheerful.
In fact, she was always happy to teach the students something new.
So it’s no surprise why they ended up loving her too.
More facts about Wilhelmina Grubbly-Plank
#1: A pretty decent teacher

A lot of students loved Hagrid.
Sure, he could be rough around the edges when it came to teaching them.
But Hagrid always meant well.
So what about Professor Grubbly-Plank?
It turned out that she was a very competent teacher too.
In fact, a lot of students enjoyed her classes.
And even Parvati Patil said:
“I hope she stays, that woman! That’s more of what I thought Care of Magical Creatures would be like… proper creatures like unicorns, not monsters…”
Plus, it wasn’t just the students Professor Wilhelmina impressed.
Even other professors were in on it.
But the best part?
Well, even the evil Dolores Umbridge couldn’t say a bad thing about her.
Because when she inspected Grubbly-Plank’s class: it was near perfect.
And if you can remember Umbridge’s dishonest speech…
It’s impressive how Professor Grubbly-Plank managed to even listen to it:
#2: She’s got very good healing skills
Professor Wilhelmina might be a substitute teacher for Care of Magical Creatures…
But does that mean she doesn’t have any other skills?
Not by a long shot.
In fact, she’s actually got some pretty good healing magic.
For instance, do you remember Harry’s pet owl, Hedwig?
Well, Hedwig got into pretty bad shape.
After he came all the way back from London.
And can you guess who offered to help?
It was none other than Professor Wilhelmina Grubbly-Plank.
In fact, she made it look like a piece of cake too.
So apart from knowing a lot about magical creatures…
Professor Wilhelmina knew how to help them best too.
Plus, even research agrees with her actions.
Because pet ownership can have great benefits for your health.
Like reducing the risk of heart disease.
And it was kind-hearted of Professor Grubbly-Plank to help Harry’s owl…
Because Harry loved and relied on Hedwig a lot.
Plus, it’s moments like these that show the best parts of the story.
And I’m reminded why I love Harry Potter so much.
#3: Had a lot of respect for Hagrid’s teaching
Sure, Wilhelmina and Hagrid never shared a class together.
But does that mean she knew nothing about Rubeus Hagrid?
Not in the slightest.
In fact, Professor Grubbly Plank had a lot of respect for Rubeus Hagrid.
And that’s because she knew that Hagrid was a great teacher.
For example, do you remember the Thestrals?
They were skeletal horses that could fly…
And it would take a lot of skill to train them.
But Hagrid managed to do it.
As a result, Professor Wilhelmina couldn’t help but be blown away.
Plus, even when Harry Potter kept asking her about Hagrid’s whereabouts.
Professor Grubbly-Plank kept her mouth shut tight.
And that’s because she knew how important it was to keep things a secret from the boy.
In fact, even a study agrees she’s the best kind of friend to have.
And that’s because that level of respect doesn’t just help build a strong bond.
But it can also increase your life satisfaction too.
Bonus: She can hold her own in a fight
Professor Wilhelmina might not be among the strongest wizards in Harry Potter…
But she can cast a non-corpreal Patronus.
The strongest defensive spell in the world.
So if things turn south…
She can actually put up a good fight.
