Editorial guidance for the earliest Superboy stories was provided by Jack Schiff, one of Detective Comics' major editors in their early years, and he continued editing Superboy until 1953, when Mort Weisinger took over on both "Superboy" and "Adventure Comics." Weisinger would later edit the entire Superman line. Over the course of the next few years, Weisinger brought in new writers and artists to work on Superboy. Perhaps the most significant new additions were writer Otto Binder, former Fawcett Comics and Marvel Family scripter, who started writing Superboy stories in 1954, and artist Al Plastino, who drew Superboy starting in 1957. Together, the two men wrote the story "The Legion of Super-Heroes" in "Adventure Comics" #247 (1958), giving birth to perhaps the most successful spinoff from the Superman family of comics. Three years earlier, Binder had also introduced Krypto in a story illustrated by Curt Swan.
