John Wood Campbell Jr. (1910–1971) was a formative figure in 20th-century science fiction literature, both as an author and editor. He began writing science fiction at age 18, and quickly made his mark with stories brimming with innovative scientific concepts and exploratory visions. Campbell's 'Invaders from the Infinite' is a classic example of his work, showcasing his talent for interstellar adventure and complex, thought-provoking narratives. This book epitomizes Campbell's ability to explore the vast possibilities of science and technology, a theme that he would revisit throughout his career. As an author, Campbell's literary style is characterized by rigorous scientific extrapolation, combined with an appreciation for the profound implications such extrapolation holds for human civilization. In 1937, Campbell took over as editor of 'Astounding Science Fiction,' a position that he would hold for several decades, reshaping the science fiction genre in the process. He is credited with steering the genre away from its pulp roots to a more sophisticated and ideologically rich literature. Under his editorship, the magazine published foundational works by genre heavyweights such as Isaac Asimov, Robert A. Heinlein, and Arthur C. Clarke. Campbell's influence extended beyond his editorial work; his 'Astounding' discussions inspired Asimov's creation of the 'Three Laws of Robotics,' an indication of his enduring impact on the conceptual framework of science fiction. Though Campbell's views later in life have been subject to criticism, his early work remains a vital part of science fiction's Golden Age canon.
