Which of these crime writers originated the slogan "Guinness is Good for You"?

Dorothy Leigh Sayers (1893-1957) was one of the most famous writers of the so-called "Golden Age of Crime", and her aristocratic sleuth, Lord Peter Wimsey is seen as one of the greatest and most endearing and enduring characters in crime fiction. She was also highly regarded as a translator and theologist.

However, Sayers also spent time in a decidedly less rarefied atmosphere than that of literature or academe! From 1922-1931 she worked as an advertising copywriter for Benson's Advertising Agency in London. Whilst she was there, arguably her most famous creation was the jingle for Guinness, a type of stout or dark beer, still hugely popular in the UK. The artist John Gilroy worked in collaboration with her, and produced the iconic image of a toucan, still very familiar.

She drew on her experiences in the world of advertising in the 1933 novel, "Murder Must Advertise", where Lord Peter goes undercover in an advertising agency to solve a murder.

Other famous authors who have worked in advertising include Salman Rushdie, Faye Weldon, and F. Scott Fitzgerald.
