The man who brought to life Doctor Who's army of Daleks has died aged 84, his daughter said.
Former BBC designer Raymond Cusick will be remembered for devising the race of mutants who move around in tank-like travel machines.
The pepper pot-shaped villains - created by writer Terry Nation - were designed by Mr Cusick based on a short description in the show's scripts.
His daughter Claire Heawood announced his death.
She said he had been suffering from an illness and died peacefully in his sleep on Thursday.
Mr Cusick, from Horsham, West Sussex, had two daughters and seven grandchildren.
Doctor Who is celebrating its 50th anniversary this year.
