S. M. Tenneshaw

S. M. Tenneshaw was a floating pseudonym, or house name, used by Ziff-Davis and related Chicago science-fiction magazines from 1947 to 1958. The name first served as a personal pseudonym for editor and publisher William Hamling, but its authorship was later shared among writers including Randall Garrett, Robert Silverberg, Milton Lesser, and Edmond Hamilton.

Because many Tenneshaw stories remain unattributed, the exact contributions of each writer are uncertain. Works published under the name include The Obedient Servant, Let Space Be Your Coffin, Trouble on Sun-side, The Friendly Killers, and The Monster, along with the novel Beyond the Walls of Space.
