Frans Le Roux sold his first comics to a local newspaper when he was fifteen years old. He went on to study graphics in Groningen, and got a job as a graphic designer. Around 1980, he picked up cartooning again and became a freelance comic artist and illustrator. He made several thousand comics, cartoons and illustrations for various employers, such as educational publishers, children's magazines and newspapers. He has made among others a juridical info comic/cartoon for VARA TV Magazine, and the comic strip 'Soetie' for Max Havelaar.
Le Roux was involved with animation for a while, and writes the scenarios for the comic series 'Arin', drawn by Roelof Wijtsma. He is also one of the initiators of the Stripmuseum in Groningen. He is specialized in large, crowded cartoons, with many details.
