Eando Binder

Eando Binder is a pen name used by two mid-20th-century science fiction authors, Earl Andrew Binder (1904–1966) and his brother Otto Binder (1911–1974). The name is derived from their first initials (E and O Binder). Under the Eando name, the Binders wrote some published science fiction, including stories featuring a heroic robot named Adam Link. The first Adam Link story, published in 1939, is titled "I, Robot".

Overview
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 Detective Comics (1948–1969), as well as numerous other publishers, with credited stories numbering over 4400. The pen-name Eando Binder is also credited with over 160 comic book stories.

Otto Binder was born in Chicago and moved to New York in 1936. He worked as a literary agent for Otis Adelbert Kline for a year, then became a free-lance writer. He sold his first story in 1930 and 129 more during the next decade. He lived in Englewood, New Jersey, from 1944 until he moved to Chestertown in 1968. Otto Binder attended Crane College in Chicago and told Amazing Stories he was once "an amateur chemist with a home laboratory."

He wrote comic-book scripts, novels, and magazine articles. His books included Riddles of Astronomy, Careers in Space, and Mankind, Child of the Stars.

He was a member of the Journal of American Literature, the American Rocket Society, the American Interplanetary Society, the National Space Flight Association, and the Aerospace Writers Association.

He died October 14, 1974, and was survived by his wife, Ione; a brother, Jack, and two sisters, Marie Hackstock of Chicago and Teresa Samuelson of Estes Park, Colorado.

Earl Binder worked as a mechanical parts inspector for a "large industrial concern" during the 1930s.
