Shadows of Eternity

Gregory Benford (born January 30, 1941) is an American science fiction author and astrophysicist who is Professor Emeritus at the Department of Physics and Astronomy at the University of California, Irvine. He is a contributing editor of Reason magazine.
Benford wrote the Galactic Center Saga science fiction novels, beginning with In the Ocean of Night (1977).
The series postulates a galaxy in which sentient organic life is in constant warfare with sentient electromechanical life.
In 1969 he wrote "The Scarred Man",the first story about a computer virus, published in 1970.
Benford was born in Mobile, Alabama and grew up in Robertsdale and Fairhope.
Graduating Phi Beta Kappa, he received a Bachelor of Science in physics in 1963 from the University of Oklahoma in Norman, Oklahoma, followed by a Master of Science from the University of California, San Diego in 1965, and a doctorate there in 1967. That same year he married Joan Abbe, with whom he had two children.
Benford modeled characters in several of his novels after his wife, most prominently the heroine of Artifact. She died in 2002.
Benford has an identical twin brother, James (Jim) Benford, with whom he has collaborated on science fiction stories.
Both got their start in science fiction fandom, with Gregory being a co-editor of the science fiction fanzine Void. Benford has said he is an atheist.
He has been a long-time resident of Laguna Beach, California.
Gregory Benford's first professional sale was the story "Stand-In" in the Magazine of Fantasy and Science Fiction (June 1965), which won second prize in a short story contest based on a poem by Doris Pitkin Buck. In 1969, he began writing a science column for Amazing Stories.
Benford tends to write hard science fiction which incorporates the research he is doing as a practical scientist.
He has worked on collaborations with authors William Rotsler, David Brin and Gordon Eklund.
His time-travel novel Timescape (1980) won both the Nebula Award and the John W. Campbell Memorial Award.
The scientific procedural novel eventually loaned its title to a line of science fiction published by Pocket Books. In the late 1990s, he wrote Foundation's Fear, one of an authorized sequel trilogy to Isaac Asimov's Foundation series.
Other novels published in that period include several near-future science thrillers: Cosm (1998), The Martian Race (1999) and Eater (2000).
