David Gerrold has been writing science fiction for fifty years, leaving a long trail of novels, scripts, short stories, columns, and articles in his wake.  He has worked on a dozen different television series, including Star Trek, Land Of The Lost, Sliders, Tales From The Darkside, Twilight Zone, and Babylon 5.  He has published over sixty novels and short story collections. Gerrold's published series are The War Against The Chtorr series (A Matter For Men, A Day For DamnationA Rage For RevengeA Season For Slaughter), The Dingilliad Trilogy (Jumping Off The PlanetBouncing Off The MoonLeaping To The Stars), and The Star Wolf Trilogy (The Voyage Of The Star WolfThe Middle Of NowhereBlood And Fire). His other novels include  the Hugo-nominated When HARLIE WAS ONE, and the Hugo and Nebula-nominated The Man Who Folded Himself. His most recent novels are thirteen, fourteen, fifteen o'clock, Jacob, and Hella. In 1994, Gerrold shared the adventure of how he adopted his son in The Martian Child, a semi-autobiographical tale of a science fiction writer who discovers his adopted child might be a Martian. The Martian Child won the science fiction triple crown:  the Hugo, the Nebula, and the Locus Poll. It was the basis for the 2007 film "Martian Child" starring John Cusack and Amanda Peet. (The book is better.) But despite all of that, David Gerrold is best known as the man who created tribbles for Star Trek, and Sleestaks for Land Of The Lost.
