Morton lived in Chertsey for many years. It was there that he wrote "Box and Cox" (1847), which "The New York Times" in 1891 called "the best farce of the nineteenth century". "Box and Cox", was wildly successful, earning him about £7000, and was translated into many European languages. A musical version, "Cox and Box" (1867), was created by F. C. Burnand and Arthur Sullivan, but Morton received no royalties from it. However, it brought him a measure of fame as it is often revived by Gilbert and Sullivan fans, helping to make it his best known work.
