Born in Namibia, Viall spent time in South Africa until 1980, when he left because of trouble with his support for the African National Congress. Upon returning to Namibia, he was one of the founders of The Namibian newspaper, and he still serves as its political cartoonist. In much of his work, Viall takes an activist stance, with the aim of providing social and political commentary on national issues. His career has ranged through the struggles of Apartheid into the fight for Namibia’s independence against South Africa, which the nation won in 1990. In addition to his work for the newspaper, he has also worked as a filmmaker and produced comic art for a number of pamphlets designed to spread awareness of social issues, such as AIDS or constitutional rights.
