Derrick Sherwin

Derrick G. Sherwin (born 16 April 1936 in, England, died 17 October 2018 ) was script editor of Doctor Who from The Web of Fear to ''The Mind Robber. Immediately after his departure as script editor, he wrote The Invasion''. He was the producer from The War Games to Spearhead from Space, overseeing the transition from Patrick Troughton's Second Doctor to Jon Pertwee's Third Doctor, the production's conversion from monochrome to colour, and the retooling of the series to one of Earth-bound, present-day adventures (DOC: The UNIT Family). However, Sherwin is the shortest-serving producer of the classic era of Doctor Who, having produced only two serials consecutively.

Sherwin, as well as being script editor and producer, was also an actor, with several roles on television in the 1950s and 1960s. He made a cameo appearance in Spearhead from Space as a UNIT commissionaire. (DOC: Down to Earth) The last acting role of his career was in The Invasion, a serial written by him, where he stepped in as a non-speaking and uncredited UNIT attendant. (DWM 533)

His wife, Jane Sherwin, whom he had met as an actor, would play Lady Jennifer Buckingham in his first story as producer, The War Games.
