Dupa was a Belgian comic book artist, known as the creator of 'Cubitus'. Born Luc Dupanloup in Montignies-sur-Sambre Luc as the son of painter André Dupanloup, he enrolled at the Academy of Fine Arts in Brussels in the 1960s. He studied there for three years before being hired by Studio Greg as a background artist on series like 'Zig et Puce' and 'Achille Talon'. He has also cooperated on 'Fifi', 'Fleurette', 'Luc Junior' and Tootsy'.
He was offered a spot in Tintin magazine in 1968, and this resulted in the creation of Dupa's famous dog 'Cubitus'. The adventures of the sympathetic, fluffy white dog gained immediate popularity, and the cast was soon enhanced by Cubitus' master, the retired sea dog Sémaphore, and the evil cat next door Sénéchal. The series remained a regular feature in Tintin throughout the 1980s, and even got its own, although short-lived, magazine in 1989. More than 100 animated shows starring 'Cubitus' ('Dommel' in Dutch, 'Wowser' in English) have been made in the mid 1990s, and have been broadcasted in Belgium and abroad. 'Cubitus' is also one of the most-featured Belgian comic characters in advertisements.
In addition, Dupa created other series, including 'Petit Biniou' from 1968 to 1970. Between 1972 and the early 1980s, he succeeded Macherot on the funny animal series 'Chlorophylle' with textwriters Greg and Bob de Groot. He has also written comic scripts for Éric ('Coup d'Oeil' and 'Le Verrou', for Dargaud in 1984), and he was co-author of 'Alice au Pays des Merveilles' together with Greg, Dany, Turk and De Groot. From 1980, he occasionally drew stories starring 'Niky', a female truck driver. Dupa passed away in Ottignies-Louvain-la-Neuve in November 2000.
