Forced to the realization that he was not having enough fun as a would-be hedonist to justify the lifestyle, he decided to become a full-time writer. On the way there he became what may be the only person to hold a Masters of Arts degree in Speculative Fiction (Goddard College). After 20 years in Paris, where he worked as a publisher's reader for several French publishers and, less artistically, as a financial translator for French brokerage houses, he now lives in Pacific Grove, California. His first novel, "Symbiote's Crown" ("l'Idiot-roi") received the French "Prix Apollo" award. This novel was science fiction. He won a World Fantasy Award for Best Short Fiction in 1985 for "Still Life with Scorpion", and has been nominated for the award three other times. Baker was co-author of the screenplay for the French film LITAN, which won the "Prix de la Critique" (Critic's Prize) at the Avoriaz Fantastic Film Festival in 1982, and has worked on a number of other French films. He wrote some of the websites for WHO KILLED EVAN CHANG?, the web tie-in for Steven Spielberg’s film, AI (Warner Brothers, 2001). He has been a judge for the World Fantasy Award and the Philip K. Dick Award. Now in semi-retirement, he devotes most of his time to playing tennis, at which he is tenacious but not particularly gifted.
