William H. Keith, Jr. was a major writer/designer for the Twilight: 2000 system.
Keith was literally “present at the creation;” he was in the rental van with fellow designers Chadwick and Wiseman when the initial concepts for the game system were hammered out. Keith started as out as an illustrator, producing hundreds of classic and iconic images for the Traveller role-playing game system. He is an award-winning novelist, with more than sixty books published or on the way (and ranging from science fiction to action-adventure to military techno-thrillers). But in the years in between, he was a game designer. His roleplaying game Behind Enemy Lines won the 1982 H.G. Wells Award for Best Role-Playing Game.
Keith also writes under various pseudonyms and "house names", including Ian Douglas and H. Jay Riker, and is a shadow author of several books "by" celebrities. He has been writing extensively in Keith Laumer's Bolo series, contributing several short stories to the Bolo anthologies, as well as full length books including, "Bolo Strike" and "Bolo Rising". As Ian Douglas, he writes a SF/military series "The Heritage Trilogy" and its sequel, "The Legacy Trilogy", and its sequel, "Inheritance Trilogy" with the premise being the U.S. Marine Corps being sent to battle alien species. As H. Jay Riker he writes a fictional series about the United States Navy SEALS progression from World War II through the Vietnam War, Desert Storm and Iraqi Freedom. He also writes a fictional series about submarine service.
Other novels include "Diplomatic Act" with Peter Jurasik. He is also continuing Keith Laumer's Retief series with "Retief's Peace", due out in September 2005.
Keith's first non-fiction book, "The Science of the Craft," was published in 2005. It is about the link between witchcraft and science.
Keith, a Wiccan and a Reiki master, is also a member of Western Pennsylvania Mensa.
