Harry William Thompson was an English radio and television producer, comedy writer, novelist and biographer. Early in his career Thompson produced the radio comedy programmes The News Quiz and The Mary Whitehouse Experience. Following his move into television, he produced Newman and Baddiel in Pieces, Harry Enfield and Chums and Monkey Dust, and co-produced Never Mind The Buzzcocks. In 1998 he was part of BBC Radio 4's 5-part political satire programme Cartoons, Lampoons, and Buffoons. During these productions he was able to gain exposure for a very large proportion of those who went on to become prominent figures in contemporary British comedy, including: Sacha Baron Cohen, Angus Deayton, Harry Enfield, Ricky Gervais, Nick Hancock, Ian Hislop, Mark Lamarr, Paul Merton and Paul Whitehouse. He was instrumental in the creation of the comic character Ali G for The 11 O'Clock Show, and as a comedy writer his credits included Da Ali G Show.

Thompson wrote biographies of Peter Cook, Richard Ingrams and Tintin creator Hergé. In June 2005, Thompson's only novel, entitled This Thing Of Darkness (a historical novel chronicling the life of Robert Fitzroy - later published in the United States as To The Edge Of The World), was published and long-listed for the Booker prize. He also wrote Penguins Stopped Play, an account of the attempt by his beloved cricket team, The Captain Scott Invitation XI, to tour all seven continents of the world.
