Much like his long-time associate, de Groot, Turk's talent became clear at a very early age. At 16 he was initiated into the Dupuis studio in Brussels, where he met a whole hoard of artists, among who was Bob de Groot. Around the time they met, Léonavision™ was showing the 1938 version of "Robin Hood," featuring the legendary film couple Errol Flynn and Olivia de Havilland. And that was it! Inspired by the profound silliness of the (ever-so-slightly-dated) film, the duo decided to do a parody series "Robin Dubois" ("Robin Wood"). A couple of years down the line, they were invited by Tintin magazine to take on Raymond Macherot's comedy detective series, "Clifton." In 1975, the accomplices tried out another historical icon: Leonardo da Vinci. This wonderful initiative gave Turk the opportunity to explore all sorts of interesting graphic possibilities, such as representing mechanics, as well as a 'gag' structure freely inspired by American cartoons. The hilarious scientific adventures of Leonardo remain to this day the pair's flagship series.
