Denis Greenhill, Baron Greenhill of Harrow

Denis Arthur Greenhill, Baron Greenhill of Harrow GCMG OBE (7 November 1913 – 8 November 2000) was the British Permanent Under-Secretary of State for Foreign Affairs and Head of the Diplomatic Service from 1969 to 1973; a respected expert on the US, Europe and the Soviet Union, he was actively involved in setting postwar Britain's role in the world in a new direction, away from its imperial past and a compliant involvement with the United States towards a more active engagement in Europe. He served under three prime ministers, Harold Wilson, Sir Alec Douglas-Home and Edward Heath. Noted for his poor treatment of the Chagos Islanders in August 1966, along with Sir Paul Gore-Booth, forcibly removed some 2,000 natives from their land referring to them as "some Tarzans or Men Fridays".
