Stone was born in
Llanelli in
Wales, and after qualifying as a doctor at
Cardiff University and
Westminster Hospital Medical School worked as a GP in and around
Hendon. He took on a number of patients from
Hampstead Garden Suburb, at the time an area popular with left-wing politicians, one of whom was Harold Wilson, who went on to become
Prime Minister of the United Kingdom. During
World War II, as a captain in the
Royal Army Medical Corps, Stone was in the
British Army force that liberated
Belsen concentration camp. He became heavily involved as a doctor in the initial army reaction to the situation they found in Belsen, and to the rehabilitation of the prisoners there. He was possibly the first British Jewish doctor to enter Belsen after its liberation. His brother-in-law,
Sidney Bernstein, was then commissioned by the
British Government to make a documentary about the liberation of Belsen and the concentration camps, which may have been influenced by the letters Stone sent home to his wife, Beryl. As a peacetime GP, his patients included
Lord Longford and Wilson, and when Wilson became prime minister, Stone became his personal physician. During this period in his career he counted a large number of Wilson's
Cabinet as his patients. Stone travelled widely with the prime minister, and became a close confidant of his. He remained a family GP in Hendon until a few years before his death, and during his time as Wilson's doctor. Stone also had a General Practice (GP) in Cricklewood Lane, London, for many years serving the local community. He was
knighted in 1970, and later was created a
life peer in the
1976 Prime Minister's Resignation Honours, taking the title
Baron Stone, of Hendon in
Greater London, on 24 June 1976. ==Death and legacy==
