Terry Nation, Welsh author and screenwriter (b. 1930)
Terence Joseph Nation (8 August 1930 – 9 March 1997) was a Welsh screenwriter and novelist. Especially known for his work in British television science fiction, he created the Daleks and Davros for Doctor Who (1963), as well as the series Survivors (1975) and Blake's 7 (1978).

Nation first made his name as a comedy writer before becoming a prolific writer for drama, working on many of the most popular British series of the 1960s and 1970s such as The Avengers, The Baron, The Champions, Department S, The Persuaders! and The Saint. When Nation was commissioned to write The Daleks (1963) for Doctor Who, the villainous eponymous creatures established the series' early popularity. He later devised the recurring character of Davros in Genesis of the Daleks (1975). His series Survivors and Blake's 7 have been described as "much-loved cult TV classics".
