Wonder Stories was an early American science fiction magazine published under several titles from 1929 to 1955. It was founded by Hugo Gernsback after he lost control of his first science fiction magazine, Amazing Stories. In 1936 he sold Wonder Stories to Ned Pines at Beacon Publications; retitled Thrilling Wonder Stories, it continued for nearly 20 years. The editors under Gernsback's ownership were David Lasser, who worked hard to improve the quality of the fiction, and later Charles Hornig. They published some well-received fiction, such as Stanley G. Weinbaum's "A Martian Odyssey", but were overshadowed by the success of their chief competitor Astounding Stories. For a period in the early 1940s the magazine was aimed at younger readers, with a juvenile editorial tone and covers that depicted beautiful women in implausibly revealing spacesuits. By the end of the 1940s, in the opinion of science fiction historian Mike Ashley, the magazine briefly rivaled Astounding. (Full article...)
