Henri Ducard was cooked up around the time of Tim Burton's blockbuster original cinematic take on the Dark Knight. He was created by "Batman" screenwriter Sam Hamm for the arc "Blind Justice" and showed up again in Dennis O'Neal's "The Man Who Falls" in the pages of the "Secret Origins of the World's Greatest Super-Heroes" trade paperback. The latter was borrowed from heavily for "Batman Begins," establishing Bruce Wayne's early training in a different light than Frank Miller's "Year One." Another story of the era, "Shaman" ("Legends of the Dark Knight"#1-5), was also a touchstone in similar ways.
