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".
