Ruben Meriggi made his comics debut in 1976 by cooperating on the 'Argón' series, written by Oesterheld and Ray Collins at the Columba publishing house. For the same publisher, he worked on series like 'Dennis Martin', 'Davide Coates' and 'Rodwin de Britania'. At the publishing house Eura, he illustrated the Oesterheld scripted 'Bull Rocket', as well as a couple of other series such as 'Almanzor' and 'Búsqueda'. At Columba, he then began the series 'Wolf' and most notably, 'Crazy Jack', which became one of the most popular Argentine series. Later on, he also produced series like 'Aar', 'Historias de Mañana', 'Ciborg' and 'Blood Town', as well as some stories with 'Conan' for Marvel.
