Otto Binder

Eando Binder is a pen-name used by two mid-20th-century science fiction authors, Earl Andrew Binder (1904-1965) and his brother Otto Binder (1911-1974). The name is derived from their first initials ("E and O Binder"). By 1939, Otto had taken over all of the writing, leaving Earl to act as his literary agent. Under his own name, Otto wrote for the Captain Marvel line of comic books published by Fawcett Comics (1941-1953) and the Superman line for DC Comics (1948-1969).
