Richard Gordon, was an English ship's surgeon and anaesthetist. As Richard Gordon, Ostlere wrote numerous novels, screenplays for film and television and accounts of popular history, mostly dealing with the practice of medicine. He was best known for a long series of comic novels on a medical theme beginning with Doctor in the House, and the subsequent film, television, radio and stage adaptations. His The Alarming History of Medicine was published in 1993, and he followed this with The Alarming History of Sex.

Doctor at Sea is a 1955 British comedy film, directed by Ralph Thomas, produced by Betty E. Box, and based on Richard Gordon's 1953 novel of the same name. This was the second of seven films in the Doctor series, following the hugely popular Doctor in the House from the previous year. Once again, Richard Gordon participated in the screenwriting, together with Nicholas Phipps and Jack Davies, and once again Dirk Bogarde played the lead character Dr Simon Sparrow. The cast also includes James Robertson Justice and Joan Sims from the first film, but this time playing different characters. This was Brigitte Bardot's first English-speaking film.
