Dennis O'Neil began his career as a comic-book writer in 1965 at Charlton, where then-editor Dick Giordano assigned him to several features. When Giordano moved to DC, O'Neil soon followed. At DC, O'Neil scripted several series for Giordano and Julius Schwartz, quickly becoming one of the most respected writers in comics.

O'Neil earned a reputation for being able to "revamp" such characters as Superman, Green Lantern, Captain Marvel - and Batman, whom O'Neil (with the help of Neal Adams and Giordano) brought back to his roots as a dark, mysterious, gothic avenger.

Besides being the most important Batman writer of the 1970s, O'Neil served as an editor at both Marvel and DC. After a long tenure as Group Editor of the Batman line of titles, he retired to write full-time.

Greg Rucka is a novelist whose work on Batman brought fresh attention to the character and to the inhabitants of Gotham City. He won the Eisner Award for Best Story with GOTHAM CENTRAL's "Half a Life."

His other DC credits include ACTION COMICS, ADVENTURES OF SUPERMAN, WONDER WOMAN, the new Batwoman adventures in DETECTIVE COMICS and SUPERMAN- WORLD OF NEW KRYPTON.

He was one of the co-writers of DC's weekly series 52. As a novelist, Rucka has nearly a dozen books to his credit, including the recent Walking Dead (Bantam).
