David Peter Renwick, born September 4, 1951, is an English television writer, renowned for his creation of the sitcom One Foot in the Grave (1990) and the mystery series Jonathan Creek (1997).
Before embarking on his full-time comedy writing career, Renwick worked as a journalist for his hometown newspaper, the Luton News.
In the late 1970s and early 1980s, Renwick collaborated with writing partner Andrew Marshall, providing material for popular sketch shows such as The Two Ronnies (1971) and Not the Nine O'Clock News (1979).
One of Renwick's most celebrated sketches was a parody of the BBC quiz program Mastermind, featuring a "Charlie Smithers" who chose to answer questions on the specialist subject "Answering the question before last."
Renwick and Marshall also wrote for the sketch show Alexei Sayle's Stuff and Spike Milligan's There's a Lot of It About.

Four years later, they adapted the screenplay into a feature film version.
In 1983, they wrote The Steam Video Company for Thames Television, a short comedy series based on very silly parodies of famous novels.
