My father, Peter Day, who has died aged 95, worked as a senior designer in the visual effects department of the BBC for nearly 30 years, creating an enormous range of material for many familiar TV programmes.
His career at the BBC involved the design and construction of models, machines, trick scenery, props and pyrotechnics for programmes such as Doctor Who, Blue Peter, It’s a Square World, Horizon, Arena, Shackleton, Some Mothers Do ’Ave ’Em, The Goodies and Dad’s Army. He was also responsible for conceiving the original design and construction of Davros, creator of the Daleks. Family and friends still delight in cheering his name when it appears on the closing credits of rerun series from time to time.
