Dr Jerry Eugene Pournelle was an American science fiction writer, engineer, essayist, and journalist, who contributed for many years to the computer magazine Byte, and from 1998 until his death maintained his own website and blog.
From the beginning, Pournelle's work centered around strong military themes. Several books describe the fictional mercenary infantry force known as Falkenberg's Legion. There are strong parallels between these stories and the Childe Cycle mercenary stories by Gordon R. Dickson, as well as Heinlein's Starship Troopers, although Pournelle's work takes far fewer technological leaps than either of these.
Pournelle served as President of the Science Fiction and Fantasy Writers of America in 1973.
