Walt Goossens is the son of the comic artist Gos, the creator of 'Le Scrameustache'. Walt followed his father's work with interest since his early childhood. He took courses from the Anderlecht Art School from the age of 12 and at age 16, he began assisting his father on his series. He contributed to the 'Scrameustache' stories for Spirou magazine from 1983, initially focusing on the lettering. He later also did the inking and eventually also assumed scripwriting and pencil work. While assisting his father on the long adventures of 'Le Scrameustache', Walt did comics with 'Les Galaxiens' on his own or with scenario-writer François Gilson.
