Dr. Brumm is never bored because something always goes wrong. But it does not matter! Whether his giant pumpkin does not want to fit through the door or his soccer players have suddenly disappeared from his TV, together with his friends Pottwal and Dacks, Dr. Brumm always comes up with a solution.

Latte Igel, the hedgehog, Tjumm, the squirrel, and Furr, the muskrat are living in a forest full of dangers. With tons of courage and wits, in the end, they always manage to outsmart their enemies. The stories of Latte Igel are written by the Finish author Sebastian Lybeck.

How does one become an illustrator?

Faculty of Design in Münster

I have studied at the Faculty of Design in Münster with Professor Marcus Herrenberger. My first commissions were to illustrate school books for Cornelsen Verlag. At the same time, I illustrated my first picture book »Herr Jambus und der Elefant«. This was a semester project.

Bauer Beck fährt weg

Two years later, I finally received my first commission for a children's book. The Swiss editor, Hans ten Doornkaat, sent me the story »Bauer Beck fährt weg« by Christian Tielmann. One year later, the book was published by Sauerländer Verlag. It was in the truest sense of the word a picture perfect start. This book has developed into a long seller. In addition, the following year, I was able to publish »Herr Jambus und der Elefant«.

Dr. Brumm versteht das nicht

I earned my diploma with the illustrated book »Dr. Brumm versteht das nicht«. This book was published in 2004 by Thienemann Verlag, which has published all my own children's and picture books to this day.

My Workplace

Hafenstraße 64

This is the building in Münster where I and my colleagues rent the upper floor for our studio. Come by and have a look during the "open door" event.

our kitchen

In addition, we have a kitchen in the hallway. Here, you meet a few of my illustrator friends during coffee and cake.

my studio

Take a peek in my studio, which I share with Michael and Günther.

my workspace

And this is my workspace. However, you won't find me there that early in the morning.


I paint with watercolors, which I use straight from the tube; I mix them in a large palette. I rarely use more than five or six colors for most pictures.


I have way too many brushes, because I can't part with them. All the way in the front you see my favorite paint brush: it's a large brush made of squirrel hair (size 14) to cover huge areas.

painting in Honfleur

Whenever I have time or during my vacation, I love to paint directly in front of the object. You can view my plein-air paintings on my watercolour-site.

A picture book is created


In the beginning, I draw a storyboard, a miniature version of the story. This way I maintain my overview. Do you recognize which one of my picture books this is?


It's still just an idea: an otter sits at the lake and fishes.


First, I create the character.


Then, I draw the background on a new sheet. So, my character is safe in case I have to erase something.


Both drawings are scanned. Cover closed!


Now, I can put both drawings together with an image editing software on my computer …


… and I can change them for as long as it takes until all fits together.


I print out an enlarged version of the finished image – the same size it has later in the book.

light table

The light table enables me to transfer the printed image easily onto my art board.

color sketch

However, before I start painting, I make a quick color sketch. This is kind of a final rehearsal for me.


I have made it! At 2 am, the picture is finally finished. I need about four months to complete a whole book.


Did you recognize the picture? No? Then go ahead and check out the Dr. Brumm page.
