Jean Giraud had one of the most interesting double lives in comics history. Under his own name, he co-created the legendary western comic 'Blueberry' (1963-2012) with writer Jean-Michel Charlier. He also used the shortened signature of "Gir" for this series. This cowboy series was noted for its highly realistic artwork and more gritty, complex and adult story lines, which had a tremendous impact on several other European western comics from the late 1960s on. Giraud also created another western series with Charlier, 'Jim Cutlass' (1979), but later wrote the stories himself while Christian Rossi provided artwork. As Moebius, he was one of the most innovative and influential comic artists of the 20th century, known for groundbreaking science-fiction and fantasy works like 'Arzach' (1975), 'The Airtight Garage of Jerry Cornelius' (1976-1979) and 'The Incal' (1980-1985).

He experimented with graphic styles, lay-out, dialogue, visuals and plot development. Its themes, highly influenced by philosophical writings and hallucinogenic drugs, elevated adult comics to another level. Moebius was at the forefront of a new wave of experimental comic authors, who gathered in the comics magazine Métal Hurlant (Heavy Metal) and the publishing label Les Humanoïdes Associés. He was active as a comics writer, screen writer, storyboard and concept designer too. Last but not least, superhero fans may know him from his mini-series based on Stan Lee and Jack Kirby's 'The Silver Surfer' (1988-1989). Both as Giraud and as Moebius he is one of the most important comics authors of all time, whose influence can be felt in several fantasy and science fiction films and video games too.
