A Bertram Chandler

A. Bertram Chandler was an Australian SF master who filled magazines such as "Astounding "with adventure and space opera extraordinaire from the 1940s into the 1970s. He was a favorite of legendary editor John W. Campbell and was a merchantman seaman commanding various ships in the Australian and New Zealand navies during much of his early life--a background Chandler puts to full use in his John Grimes stories.
