King Edward VII's Hospital

King Edward VII's Hospital (formal name: King Edward VII's Hospital Sister Agnes) 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 (later King Edward VII) 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. He was admitted again in 1963. In 1948, following the Second World War, the hospital moved to Beaumont Street where the current premises were opened by Queen Mary. It has also treated members of the British royal family.

In December 2012, the hospital received international media attention when, while Catherine, Duchess of Cambridge was staying there, two DJs from the Australian radio station 2Day FM made a hoax telephone call to the hospital. Soon afterwards, nurse Jacintha Saldanha, who had passed on the hoax call to the other nurse in the Duchess's private ward, was found dead.
