Jeroen Steehouwer began his comics career with the magazine Sjors en Sjimmie with such series as "Fanteasy" (scenarios by Fred Julsing, 1987-88) and "Roy Bellevue" (scenarios by Hanco Kolk, 1989). In 1990 he co-founded Funny Farm, the comic studio that published the magazine Razzafrazz. For this magazine, Steehouwer produced several independent stories, including "Honorary Guilt," with a screenplay by M. Daalder and P. van Dongen. Steehouwer ran his own Hildebrand Studio, through which he self-published Hildebrand Comix. He illustrated stories with "Winnie the Pooh" and "Little Hiawatha" for the Dutch Disney production in the early 1990s, and in 1994 he started his gag strip "Katja" in Suske en Wiske Weekblad. For the same magazine, between 1998 and 2001, he created the adventure series 'Pelle' with Frans Leenheer and scriptwriter Willem Ritstier.
