Robert Kanigher has long been recognized as one of the most prolific and innovative writers and editors in the comic book industry. Since the 1940s, Kanigher wrote and/or created more characters than nearly anybody else in the field, including Batman, Blue Beetle, Steel Sterling, Black Canary, Captain Marvel, the Flash, Sgt. Rock, the Haunted Tank, Wonder Woman, Lois Lane, and innumerable war, horror, and romance scripts. Kanigher scripted the Silver Age Flash's origin story in Showcase #4 and contributed several more tales to his subsequent Showcase appearances before finally returning to the character for an extended run as regular writer on The Flash in 1970. Kanigher passed away in 2002.
