William F. Jenkins, known to science fiction fans by his penname Murray Leinster, was among the most prolific American writers of the 20th century. "The Dean of Science Fiction," as he was sometimes known, published over 1,500 short stories and 100 books in a career spanning more than 50 years. This biography, written by his two youngest daughters, chronicles Murray Leinster's private and literary life from his first writings for The Smart Set and early pulp magazines such as Argosy, Amazing Stories and Astounding Stories, through the golden age of science fiction in the 1930s through the 1950s, to his death in 1975. Included are a short story and essay by Leinster, as well as previously unpublished poetry and letters.
