Eando Binder is a pseudonym for two brothers, Earl Andrew Binder (1904–1965) and Otto Binder (1911–1974), who were science fiction authors in the mid-20th century. The name is derived from their first initials ("E and O Binder") and should perhaps be regarded as a "parapseudonym". In practice, many of the works of Eando Binder were written by Otto alone.
Under the Eando Binder 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". Isaac Asimov was said to have been distraught upon learning that his prelude to the Robot Series was also going to be released under this title (he supposedly preferred Mind and Iron).
