John W. Campbell, Jr.

John W. Campbell (June 8, 1910 – July 11, 1971) was the editor of Astounding Science Fiction from 1937 until his death in 1971. After being a well-known author in his own right, he then devoted himself exclusively to editing and helped launch the careers of most of the key figures in what is generally known as the Golden Age of Science Fiction, including Robert A. Heinlein, Isaac Asimov, Theodore Sturgeon, A.E. van Vogt, and Arthur C. Clarke . Although Campbell had many eccentricities, some of which, such as a belief in psionics, later found their way into his publications in the 1950s and '60s, he remains, almost without question, the single most important figure in the development of modern science fiction, with the possible exception of his protégé Robert Heinlein.
