King Edward VII's Hospital

King Edward VII's Hospital is a private hospital located on Beaumont Street in the Marylebone district of central London.

Agnes Keyser, later known as Sister Agnes, established the hospital in her home at 17 Grosvenor Crescent in 1899 in the wake of the Second Boer War and at the suggestion of the Prince of Wales who went on to become the hospital's patron. Its first intake of sick and mostly gunshot-wounded British Army officers arrived in February 1900.

The hospital continued to operate during peacetime. During the First World War it continued to specialise in treatment of wounded officers by a select group of honorary staff, drawn up by Sister Agnes and made up of eminent London surgeons of the time. Military personnel treated included the future prime minister Harold Macmillan who was injured in 1916.
