He was born in 1951 in Leonding near Linz. For twelve years he worked as a graphic designer and illustrator for advertising agencies. In 1985, he lost interest in the industry and started drawing cartoons. His first works appeared in the small satire magazine "Watzmann" in Salzburg, then regularly in "profile", from 1992 to 2016 in "stern" and since then weekly in NEWS. In addition to a series of cartoon anthologies, Gerhard Haderer draws and writes books with picture narratives. His 2002 book "The Life of Jesus" triggered intense international reactions. Since 2002 "MOFF - Haderers feines Schundheftl" is published monthly, a comic project in the classic piccolo format. Gerhard Haderer's graphic work has received many awards and his works are shown in solo exhibitions in the German-speaking world.
