Korean-American comic book artist and writer whose works included "Batman: Hush" and "Superman: For Tomorrow." He co-founded Image Comics in 1992 for creator-owned titles, including his own "WildC.A.T.s" and "Gen¹³" from his Wildstorm Productions.
He studied psychology at Princeton University and originally intended to become a medical doctor. He was hired as an artist by Marvel Comics in 1987, where he worked on "Alpha Flight" and "Punisher War Journal," before gaining fame on "The Uncanny X-Men," the sales of which broke all existing records.
He was named Co-Publisher of DC Comics, alongside Dan DiDio, in February 2010, replacing the longtime head, Paul Levitz.
His family was a rather ordinary middle-class clan residing in St. Louis, Missouri. He married Carla Michelle Lee.
He was interviewed by Stan Lee for the documentary film, "The Comic Book Greats," from 1991.
