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.
