Mike Mignola was born September 16, 1960 in Berkeley, California and grew up in nearby Oakland. His fascination with ghosts and monsters began at an early age (he doesn't remember why) and reading Dracula at age 13 introduced him to Victorian literature and folklore from which he has never recovered. In 1982, hoping to find a way to draw monsters for a living, he moved to New York City and began working for Marvel Comics, first as a (very terrible) inker and then as an artist on comics like Rocket Raccoon, Alpha Flight and The Hulk. By the late 80s he had begun to develop his signature style (thin lines, clunky shapes and lots of black) and moved onto higher profile commercial projects like Cosmic Odyssey (1988) and Gotham by Gaslight (1989) for DC Comics, and the not-so-commercial Fafhrd and the Grey Mouser (1990) for Marvel. In 1992, he drew the comic book adaptation of the film Bram Stoker's Dracula for Topps Comics. In 1993, Mike moved to Dark Horse comics and created Hellboy, a half-demon occult detective who may or may not be the Beast of the Apocalypse. While the first story line (Seed of Destruction, 1994) was co-written by John Byrne, Mike has continued writing the series himself. There are, at this moment, 13 Hellboy graphic novel collections (with more on the way), several spin-off titles (B.P.R.D., Lobster Johnson, Abe Sapien and Witchfinder), three anthologies of prose stories, several novels, two animated films and two live-action films staring Ron Perlman. Hellboy has earned numerous comic industry awards and is published in a great many countries. Mike also created the award-winning comic book The Amazing Screw-on Head and has co-written two novels (Baltimore, or, the Steadfast Tin Soldier and the Vampire and Joe Golem and the Drowning City) with best-selling author Christopher Golden. Mike worked (very briefly) with Francis Ford Coppola on his film Bram Stoker's Dracula (1992), was a production designer on the Disney film Atlantis: The Lost Empire (2001) and was visual consultant to director Guillermo del Toro on Blade II (2002), Hellboy (2004) and Hellboy II: The Golden Army (2008). He lives somewhere in Southern California with his wife, daughter, a lot of books and a cat.

Librarian note: There is more than one author in the GoodReads database with this name John Lindley Byrne is a British-born Canadian-American author and artist of comic books. Since the mid-1970s, Byrne has worked on nearly every major American superhero. Byrne's better-known work has been on Marvel Comics' X-Men and Fantastic Four and the 1986 relaunch of DC Comics’ Superman franchise. Coming into the comics profession exclusively as a penciler, Byrne began co-plotting the X-Men comics during his tenure on them, and launched his writing career in earnest with Fantastic Four (where he also started inking his own pencils). During the 1990s he produced a number of creator-owned works, including Next Men and Danger Unlimited. He also wrote the first issues of Mike Mignola's Hellboy series and produced a number of Star Trek comics for IDW Publishing.
