Christopher H Bidmead trained as an actor at the Royal Academy of Dramatic Arts (RADA) and pursued this career for a number of years, winning many roles on stage, television (he was a regular in "Emergency Ward 10") and radio (including numerous episodes of the BBC's "Waggoner's Walk"). Gradually however he turned to scriptwriting, including in the early seventies on two Thames TV shows, "Harriet's Back in Town" and "Rooms." He then worked successfully as a journalist, specialising in scientific and technical subjects, until late 1979 when he was recommended by Robert Banks Stewart for the post of script editor on Doctor Who. Having remained in this post for a year, and having also written two stories in the form of "Logopolis" and "Castrovalva," Bidmead returned to freelance projects - including a third Doctor Who story, "Frontios," and novelisations of all three for Target books. He continues to work as a scientific and technical journalist, including on the magazine, "Wired."
