In the United Kingdom, surgeons are distinguished from physicians by being referred to as "Mister." This tradition has its origins in the 18th century, when surgeons were barber-surgeons and did not have a degree (or indeed any formal qualification), unlike physicians, who were doctors with a university medical degree.By the beginning of the 19th century, surgeons had obtained high status, and in 1800, the Royal College of Surgeons (RCS) in London began to offer surgeons a formal status via RCS membership. The title Mister became a badge of honour, and today only surgeons who hold the Membership or Fellowship of one of the Royal Colleges of Surgery are entitled to call themselves Mister, Miss, Mrs or Ms. In contrast, American physicians and surgeons are always addressed as "Doctor."
