Nahum Ziersch was born and raised in the Clare Valley in South Australia. From a very young age he knew he wanted to draw for a living, surrounded by very artistic parents who encouraged and nurtured his passion. As a kid he would watch Astro Boy and stacks of other cartoons in his PJs, devour comics and draw his own imaginative worlds and characters. Nahum works as a freelance illustrator in Adelaide. While his main areas of work include editorial, advertising and educational illustrations, he still has a mad passion for creating quirky and expressive characters.
