Biography: John and his brother Piet were active during the Second World War in their chosen profession, animation. They produced a two minute animated short featuring their creation 'Bim'. John wrote the script and dialogue, with Piet handling the animation. Failing to get funding for a longer film during the harsh war years, they turned to cartooning, creating newspaper strips starring Bim and later Ridder Rudolf. Sometime during the War, John was imprisoned by the German occupier and sent to several concentration camps. He was pronounced dead on arrival in Neuengamme after a transport from (presumably the concentration camp near the city of) Porta Westfalica.
