Charles Ian Orr-Ewing, Baron Orr-Ewing, OBE (10 February 1912 – 19 August 1999) was a British Conservative politician.
Orr-Ewing was a great-grandson of Sir Archibald Orr-Ewing, Bt. He was educated at Harrow School and Trinity College, Oxford. At Trinity College he qualified as an electrical engineer, with an MA in physics. Then, as a 22-year-old graduate apprentice at EMI in 1934, he was part of a team of three which built the first production television set.[1]
Orr-Ewing worked with the BBC from 1937 until 1939, when he joined the Royal Air Force Volunteer Reserve and served in the North Africa, Italy and North-West Europe theatres during World War II and was also General Eisenhower's Chief Radar Officer in 1945. He was appointed an Officer of the Order of the British Empire (OBE) in 1945. After the war, he returned to the BBC until 1949.
Orr-Ewing's political career began in 1950, when he was elected Member of Parliament for Hendon North, a seat he held for five elections. During this time, he was: Parliamentary Private Secretary to Walter Monckton, the Minister of Labour, from 1951 to 1955; Parliamentary Under-Secretary to George Reginald Ward, the Secretary of State for Air, from 1957 to 1959; Parliamentary and Financial Secretary to the Admiralty in 1959; Civil Lord of the Admiralty from 1959 to 1963; Vice-President of the Parliamentary and Scientific Committee in 1966 and Vice-Chairman of the Defence Committee from 1966 to 1970.
Between 1951 and 1954, he served on the Council of the Royal Television Society.[2]
Having been created a baronet in 1963, Orr-Ewing retired from the House of Commons in 1970 and was created a life peer on 30 April 1971, as Baron Orr-Ewing, of Little Berkhamsted in the County of Hertfordshire.
Orr-Ewing was an amateur radio enthusiast, holding the call sign G5OG until his death. The format of his call sign indicates that his licence was issued between 1921 and 1939. In November 1976 during the opening of Parliament, prior to his announcement of Presidency of the Radio Society of Great Britain, George Wallace, Baron Wallace of Coslany quipped that Orr-Ewing held an amateur licence and that he was colloquially known as "George Five Old Girl", a play on his call sign using non-standard phonetic alphabet.[3] Orr-Ewing died on 19 August 1999.[4]
