S. M. Tenneshaw

‘S. M. Tenneshaw’ was a floating house pseudonym used across the Ziff-Davis and Chicago magazines (Amazing, Imagination, Imaginative Tales) from 1947 to 1958. It began as a personal pen name of William Hamling but was later used by many hands, Randall Garrett (sometimes with Robert Silverberg), Silverberg solo, Milton Lesser and Edmond Hamilton among them. The name credits a magazine stable, not an author.
