Brian Finch
Brian Finch was a prolific television and occasional film writer whose career spanned from 1966 to 2006. He wrote the original television version of Leviathan but after the original plans for Season 26 were dropped in favour of Trial of a Time Lord, his script was adapted for audio release by his son Paul Finch.
Outside Doctor Who, he has written 150 episodes of Coronation Street, and recieved a BAFTA for writing the ITV drama Goodnight, Mister Tom. He also wrote several early episodes of All Creatures Great and Small, and therefore played a part in making Peter Davison a household name.
He died in June 2007, after a very short retirement from being one of the main writers of Heartbeat. At the time of his death, his failed contribution to Doctor Who was largely unknown by the fan community, and The Lost Stories range hadn't even been proposed by Big Finish. He is thus the rare example of a writer who only made a posthumous contribution to the body of published Doctor Who fiction.
