The Legion of Space by Jack Williamson

The Legion of Space, the opening salvo of a tetralogy that Jack Williamson wrote over a nearly 50-year period, was initially released as a six-part serial in the April-September 1934 issues of Astounding Stories. (This was some years before the publication changed its name to Astounding Science-Fiction, in March 1938, and, with the guidance of newly ensconced editor John W. Campbell, Jr, became the most influential magazine in sci-fi history.) It was ultimately given the hardcover novel treatment in 1947.
