His full name is Pieter Cornelis Wijn he was born in Hilversum and was hired by Toonder Studio's at the age of eighteen. His first comic, De Zwarte Hertog, appeared in the 'Tom Poes' weekly. At the age of nineteen he started working as a freelancer.
Although he's known for many comics he's mostly known for his work on De Avonturen van Douwe Dabbert. He drew the whole series, even after he was struck with a stoke and lost most of the function of his right arm he thought himself to draw with his left hand. The last few years of his life saw little productivity due to his deteriorating health. The last Douwe Dabbert story (De Avonturen van Douwe Dabbert #23 - De wonderlijke raamvertelling) was mostly drawn by Dick Matena. His close friend and co-creator of Douwe Dabbert, Thom Roep, announced on Oktober 7th, 2010 that Piet had died the day before.
