British Overseas Airways Corporation
On 24 November 1939, BOAC was created by Act of Parliament to become the British state airline, formed from the merger of Imperial Airways and British Airways Ltd. The companies had been operating together since war was declared on 3 September 1939, when their operations were evacuated from the London area to Bristol. On 1 April 1940, BOAC started operations as a single company. Following the Fall of France (22 June 1940), BOAC aircraft kept wartime Britain connected with its colonies and the allied world, often under enemy fire, and initially with desperate shortages of long-range aircraft. During the war, the airline was sometimes loosely referred to as 'British Airways', and aircraft and equipment were marked with combinations of that title and/or the Speedbird symbol and/or the Union Flag.
British Optical Association
After a peripatetic existence in Rochdale, Blackpool and London, an 'Association House' was eventually acquired in 1914 at Cliffords Inn Hall, a former Inn of Chancery close to the former Public Records Office. From 1934, when that building was compulsorily purchased for demolition, and until 1978, the BOA was housed at 65 Brook Street, Mayfair.
The British Optical Association Museum was founded in London, England, by John H. Sutcliffe OBE in January 1901 as a collection of historic spectacles and visual aids designed to illustrate the development of corrective eyewear. It subsequently expanded its collecting activities to encompass ophthalmic instrumentation and the depiction of optometric subject matter in works of art such as paintings, prints and sculpture. With over 27,000 catalogued objects (including archives) it may be judged one of the most comprehensive and high quality collections of its type. It is believed to be the oldest such museum to be open to the public. Many of its objects are rare survivals and several are unique.
