Doctor Who: The Lost TV Episodes Collection Three

Brian Hayles wrote for radio, television and film, including such series as The Archers, United! and Z Cars. Hayles' work on Doctor Who included adventures for the first three Doctors. His first story was the well-remembered 'The Celestial Toymaker', and after his historical adventure 'The Smugglers', Hayles wrote 'The Ice Warriors' - introducing the creatures for which he is best remembered. He wrote three further Ice Warriors stories, the last two featuring the Third Doctor and set on the feudal planet Peladon. Brian Hayles died in 1978.

Gerry Davis became a BBC story editor in 1965 at the invitation of Head of Serials Donald Wilson, who had been impressed by a course he had written on TV scriptwriting. He had previously been a newspaper reporter, a merchant seaman and a writer for the Canadian Broadcasting Corporation, and had studied opera and worked as a cinema translator in Italy. His first BBC assignments were on 199 Park Lane and United! and he was then given the chance to take over from Donald Tosh on Doctor Who. Although he never saw entirely eye to eye with producer Innes Lloyd, he remained in this post for over a year before moving on to edit another show, First Lady. He later returned to freelance writing, his greatest success coming in the early Seventies with the BBC's ecological drama Doomwatch, which he co-created with Kit Pedler. From the mid-Seventies he spent most of his time in Hollywood, writing for American films and TV series and teaching screen-writing courses at the UCLA Film School. He died on 31 August 1991, aged sixty-four.

David Whitaker was the first Story Editor for Doctor Who, and was responsible for finding and commissioning writers, and it was Whitaker as much as anyone who defined the narrative shape of Doctor Who. He wrote for the Doctor Who annuals, novelised the first Dalek story and worked with Terry Nation on various Dalek-related material including the hugely successful comic strip The Daleks. David Whitaker died in 1980.

Terry Nation started as a comedy writer and performer, and was approached with an offer to work on Doctor Who, providing the seven episodes of the first ever Dalek story. After inventing the Daleks, Nation moved on to work on The Saint, The Champions and The Avengers. In the 1970s he scripted four more Dalek series - including Genesis of the Daleks which has been voted the best ever story in the series. Nation later devised the hugely popular BBC science fiction series Blake's 7. Terry Nation died in Los Angeles in 1996.
