On the death of Queen Victoria in 1901, the Prince became King Edward VII and he subsequently became the hospital's first patron. In 1904 the hospital was officially named King Edward VII's Hospital for Officers and continued to care for military officers during peacetime. That year, the hospital moved to 9 Grosvenor Gardens. In the same year, eight years after retiring from the
Indian Medical Service with the rank of honorary Colonel,
Peter Freyer became a member of the honorary medical staff of the hospital, and remained there until 1909, the same year in which the constitution of the hospital was modified.
First World War The hospital had 16 beds in 1914, by which time, 1,500 officers had passed through. A few days before the onset of the
First World War, Sister Agnes drew up a list of 21 honorary staff who would predominantly be the medical men of choice treating wounded officers at 9
Grosvenor Gardens without a fee.
John Percy Lockhart-Mummery became a significant name on the list, probably carried out more operations at the hospital than any other surgeon there, and treated mainly gunshot wounds affecting the colon, rectum and anus.
John Thomson-Walker became
urologist to the hospital and concentrated on injuries to the
genitourinary tract, and for complex
operations on the bones Sister Agnes would call upon
Sir William Arbuthnot Lane. The future British Prime Minister,
Harold Macmillan, was also wounded in the same battle and was treated at the hospital, where he underwent a series of long operations followed by recuperation there from 1916 to 1918.
General Sir Joseph Howard Nigel Poett later recounted in his autobiography (1991) that Sister Agnes had arranged for his treatment to be transferred from Cambridge Hospital to King Edward VII's and that she "was a pretty powerful lady". Other officers treated at the hospital during the war have also recounted events of their stay. During the war,
Margaret Greville opened up
Polesden Lacey for the purpose of being a convalescent home linked to King Edward VII's Hospital for Officers.
Interwar In 1930, the hospital was awarded a
royal charter "to operate an acute Hospital where serving and retired officers of the Services and their spouses can be treated at preferential rates." The council first met on Armistice day of that year. From that date it was chaired by
Sir Harold Augustus Wernher until 1969. which had been renovated by the architect
Thomas Bennett & Sons.
Mountbatten, upon hearing the names of previous members of council, put his own name forward and was elected a member in 1955. The general medical officer at the hospital, working closely with Saxby at the time was
Brian Warren. On 10 October 1963, at the hospital,
Alec Badenoch, assisted by his juniors
David Innes Williams and
Joseph Smith, performed prostate surgery on Harold Macmillan. Eight days later, he was visited by
Queen Elizabeth II, the second time a sovereign had visited a prime-minister on their sick bed.
Princess Anne and the
Queen Mother were both treated at the hospital the following year in 1964. In December 1966, the Queen Mother underwent an operation at the hospital, to remove a bowel tumour. In 1967,
Princess Margaret appeared in headline news when she was admitted with acute tonsillitis. Margaret Dalglish became matron in 1969, In the interim Prince Edward, Duke of Kent became president of council, and it was subsequently chaired by
Sir Peter Hunt from 1978 to 1987, and
Sir Henry Leach from 1987 to 1998, when
Lord Craig took over. File:John Percy Lockhart-Mummery portrait.jpg|John Percy Lockhart-Mummery, who operated during the First World War.
