Harold Harington Balfour, 1st Baron Balfour of Inchrye, MC & Bar, PC (1 November 1897 – 21 September 1988) was a Conservative Party politician in the United Kingdom, and a flying ace of the First World War. As Under-Secretary of State for Air in 1944 he was instrumental in the establishment of London Heathrow Airport. Balfour was born in Camberley, Surrey, on 1 November 1897 to Colonel Nigel Harrington Balfour (1873-1955), and Grace A A Maddocks, and educated at Chilverton Elms School, Dover, Kent and later at the Royal Naval College, Osborne, Isle of Wight. Balfour joined the 60th Rifles in 1914 and served in France for three months before he transferred to the Royal Flying Corps. After training he was posted to No. 60 Squadron. In 1917 he was serving with No. 43 Squadron when he downed two enemy aircraft while flying a Sopwith 1½ Strutter. He was injured in a crash and moved on to the School of Special Flying, No. 40 Squadron, then returned to No. 43 Squadron. Now piloting the Sopwith Camel he claimed 7 more victories and was promoted to major. Balfour then took command of a training school until 1919. He was private secretary and Aide-de-camp to Air Vice Marshal Sir John Salmond 1921–22 and temporary ADC to Sir Samuel Hoare, Secretary of State for Air, 1923. He retired from the Royal Air Force in 1923 to follow a career in journalism and business. Balfour was interviewed on 30 September 1978 by the art historian Anna Malinovska. The interview is reproduced in Voices in Flight (Pen & Sword Books, 2006) Balfour contested Stratford without success in 1924 and was elected in 1929 as Member of Parliament (MP) for Isle of Thanet. He served in the Air Ministry from 1938 and was Minister Resident in West Africa, 1944–45. He was sworn in as a member of the Privy Council of the United Kingdom in 1941. He left the House of Commons in 1945 and was raised to the peerage as Baron Balfour of Inchrye, of Shefford in the County of Berkshire. Balfour died on 21 September 1988 aged 90. He was married twice in 1921 and 1946 with a son from the first marriage to Diana B Harvey, and a daughter from the second. His 2nd wife was Mary Ainslie Profumo (d.1999), sister of the disgraced cabinet minister, John Profumo. After Profumo resigned and Lord Hailsham attacked his morals, Balfour remarked on live television, "When a man has by self-indulgence acquired the shape of Lord Hailsham sexual continence requires no more than a sense of the ridiculous". Balfour's son, diamond historian Ian Balfour (b. 21 December 1924, d. 14 April 2013, aged 88), became the 2nd Baron Balfour of Inchrye on his father's death; he married Josephina Maria Jane Bernard in 1953 - they had a son.
