From Wikipedia & Happy Belated Birthday Alan Moore!
Alan Oswald Moore (born 18 November 1953) is an English writer primarily known for his work in comic books, a medium where he has produced a number of critically acclaimed and popular series, including Watchmen, V for Vendetta, and From Hell. Frequently described as the best graphic novel writer in history,(p10)(p7) he has also been described as "one of the most important British writers of the last fifty years". He has occasionally used such pseudonyms as Curt Vile, Jill de Ray, and Translucia Baboon.
Moore started out writing for British underground and alternative fanzines in the late 1970s before achieving success publishing comic strips in such magazines as 2000 AD and Warrior. He was subsequently picked up by the AmericanDC Comics, and as "the first comics writer living in Britain to do prominent work in America",(p7) he worked on big name characters such as Batman (Batman: The Killing Joke) and Superman (Whatever Happened to the Man of Tomorrow?), substantially developed the character Swamp Thing, and penned original titles such as Watchmen. During that decade, Moore helped to bring about greater social respectability for the medium in the United States and United Kingdom,(p11) and has subsequently been credited with the development of the term "graphic novel" over "comic book". In the late 1980s and early 1990s he left the comic industry mainstream and went independent for a while, working on experimental work such as the epic From Hell, pornographic Lost Girls, and the prose novel Voice of the Fire. He subsequently returned to the mainstream later in the 1990s, working for Image Comics, before developingAmerica's Best Comics, an imprint through which he published works such as The League of Extraordinary Gentlemenand the occult-based Promethea.
Moore is a Neopagan, occultist, ceremonial magician, wizard, vegetarian and anarchist and has featured such themes in works including Promethea, From Hell and V for Vendetta, as well as performing avant-garde spoken word occult "workings" with The Moon and Serpent Grand Egyptian Theatre of Marvels, some of which have been released on CD.
Despite his own personal objection to them, his books have provided the basis for a number of Hollywood films, including From Hell (2001), The League of Extraordinary Gentlemen (2003), V for Vendetta (2005) and Watchmen(2009). Moore has also been referenced in popular culture, and has been recognised as an influence on a variety of literary and television figures including Neil Gaiman,Joss Whedon, and Damon Lindelof.
