Jean Henri Gaston Giraud (French: [ʒiʁo]; 8 May 1938 – 10 March 2012) was a French artist, cartoonist, and writer who worked in the Franco-Belgian bandes dessinées (BD) tradition. Giraud garnered worldwide acclaim under the pseudonym Mœbius (/ˈmoʊbiəs/;[1] French: [mø.bjys]), as well as Gir (French: [ʒiʁ]) outside the English-speaking world, used for the Blueberry series—his most successful creation in the non-English speaking parts of the world—and his Western-themed paintings. Esteemed by Federico Fellini, Stan Lee, and Hayao Miyazaki, among others,[2] he has been described as the most influential bande dessinée artist after Hergé.[3]

His most famous works include the series Blueberry, created with writer Jean-Michel Charlier, featuring one of the first antiheroes in Western comics. As Mœbius, he created a wide range of science-fiction and fantasy comics in a highly imaginative, surreal, almost abstract style. These works include Arzach and the Airtight Garage of Jerry Cornelius. He also collaborated with avant-garde filmmaker Alejandro Jodorowsky for an unproduced adaptation of Dune and the comic book series The Incal.

Mœbius also contributed storyboards and concept designs to numerous science-fiction and fantasy films, such as Alien, Tron, The Fifth Element, and The Abyss. Blueberry was adapted for the screen in 2004 by French director Jan Kounen.
