In American English, Salisbury steak is an upmarket name for a hamburger. It commemorates J. H. Salisbury (1823–1905), a doctor well known for his public pronouncements on dietary matters. One of his hobbyhorses was the hamburger, which he recommended people to eat three times a day. The term is first recorded in 1897, but it really came into its own during the First World War, when patriotic Americans took exception to the German hamburger (compare liberty cabbage). It has continued to be used on menus in the sort of restaurant that would not own up to selling hamburgers.
