Jerry Eugene Pournelle (born August 7, 1933) is an American science fiction writer, essayist and journalist who contributed for many years to the computer magazine Byte and has since 1998 been maintaining his own website/blog.
From the beginning, Pournelle's work has engaged strong military themes. Several books are centered on a 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 was one of the few close friends of H. Beam Piper and was granted by Piper the rights to produce stories set in Piper's Terro-Human Future History. This right has been recognized by the copyright owner of the Piper estate. Pournelle did work for some years on a sequel to Space Viking but seems to have abandoned this in the early 1990s.
Pournelle served as President of the Science Fiction and Fantasy Writers of America in 1973.
