Wim Stevenhagen studied art at the Rietveld Academie in Amsterdam together with his childhood friend Gerrit de Jager. He debuted with De Jager with a series of short animations for the VARA TV quiz 'Twee voor twaalf' in 1975. They assumed the joint pseudonym Prutswerk to create comics for the alternative magazines De Vrije Balloen and Gummi, including 'De Ironische Man', 'Pruts Pruts, Private Kreye' and 'Bert J. Prulleman'. They also created 'De Familie Doorzon' in Nieuwe Revu and 'Roel en zijn Beestenboel' in Jippo.
The first 'Doorzon album', published in 1980, won them the Stripschapspenning. Stevenhagen and De Jager ended their collaboration in 1984, and while De Jager continued 'Doorzon' and 'Roel en zijn Beestenboel', Stevenhagen continued 'Bert J. Prulleman' and began a string of educational comics and illustrations. Among his production are 'Bertus Braafjes' for Milieudefensie, 'Han Gewetensvim' for Onze Wereld, 'Bob en Bertha' for Eigen Huis Magazine, 'Bob A.' for Het Schoolblad and 'Henk Vanderspatie' for Pers. Several collections of his cartoons work have appeared, such as 'Bijverschijnselen', a collection of cartoons he made about the health service, and 'Ja Ja, Maak er maar een Grapje van!', which contains political cartoons.
