Having studied in a school of applied arts and advertising, Gerhard Haderer worked for advertising agencies and as an illustrator. In 1985, tired of his activities, he turned to political cartoons. His cartoons are published in the Austrian magazine Profil and in the German weekly magazine Stern. In 2002, the release of his album “Life of Jesus” created a storm of controversy by staging a somewhat atypical Jesus. The Cardinal Archbishop of Vienna even asked Gerhard to apologise to Christians.
