Gardner F. Fox (1911-1986) wrote comics for decades. He invented Batman's utility belt, as well as creating such long lasting characters as The Flash and Hawkman. He also introduced the concept of "multiverse' to DC storytelling. He would leave comics in 1968 to try his hand at actual S&S books, penning the Kothar the Barbarian series (1969-1970), the Kyrik series (1975-1976) and finally the Niall of the Far Travels for Dragon Magazine (1976-1981).
