Herr Seele, the pseudonym of Peter van Heirseele (Torhout, Belgium), is a Flemish cartoonist, author, actor, piano tuner and piano collector.
He is mainly known for the absurd humor comic strip Cowboy Henk, for which his colleague Kamagurka writes the scripts, while he makes the drawings. The comic has been published in Humo since 1981 with only a minor interruption from October 2011 until the spring of 2013. During this period Seele made another gag-a-day comic series Dikke Billie Walter. Since the spring of 2013 Cowboy Henk appears in the magazine again.
