Moebius

Even if you don't know the name Moebius, you know his work or its influence. A French cartoonist and illustrator, Moebius was the science fiction pen name of Jean Gireaud. When he did cowboy comics, he signed GIR, when he did science fiction, he signed Moebius, but the work was always undeniable.

Moebius got his start in film concept art from the (now infamous) failed Dune adaptation, of the 70's, but went on, through the contacts he'd made, to work on Alien, Tron, The Abyss, and The Fifth Element.
