Born in Turnhout,[1] his parents moved to Antwerp a few years after his birth, looking for employment.

He was taught drawing by his father and as a child entered the youth organisation Chiro Flanders.

[3] Halfway through 1967 he decided without an appointment, with a self-drawn comic strip, to visit Willy Vandersteen in order to possibly get his dream job here.

[2] In 1971, after working in the drawing team for three years, Paul Geerts decided he would write his own comic strip for the German weekly Stern.

Geerts agreed, and in 1972 he wrote his first screenplay for a Spike and Suzy story, De gekke gokker.
