Allan George Bromley (1947–2002) was an Australian historian of computing who became a world authority on many aspects of early computing and was one of the most avid collectors of mechanical calculators.〔Graeme Philipson, (Allan Bromley: historian, eccentric, gem ), 27 August 2002.〕〔Michael R. Williams, (Allan Bromley ), ''IEEE Annals of the History of Computing'', 22(4):3, October–December 2000.〕 His work on understanding Charles Babbage's calculating engines is Allan Bromley's greatest legacy. The October–December 2000 issue of the ''IEEE Annals of the History of Computing'' was dedicated to him for the quality of his research on this subject.〔〔(''IEEE Annals of the History of Computing'', 22(4), October–December 2000 ).〕 His studies of the Antikythera mechanism, in collaboration with Michael T. Wright, led to the first working model of this ancient analogue computer.〔The University of Sydney News, 29 March 1988, p.39〕 Allan Bromley was an associate professor at the University of Sydney. His main academic interest was the history of computers. He died of Hodgkin's lymphoma. ==Collections== Dr. Allan Bromley started collecting mechanical calculators in 1979. A year later he already had sixty pieces.〔The Gazette, May 1980, p.24〕 Eventually he was responsible for a collection of old computers which used to be displayed in the rear foyer of the building containing the University of Sydney Computer Science Department. At home, he had a large personal collection of mechanical calculators, slide rules, etc. He was a generous donor of artefacts to museums in Australia, especially the Powerhouse Museum in Sydney, and the Australian Computer Museum Society Inc. His collection included some rare pieces. The pride of place was taken by four mechanical anti-aircraft gun predictors developed and built by the British government after World War I. These machines, weighing about half a tonne, marked the height of mechanical computation; they were first used in the Spanish Civil War and extensively during World War II. They performed in real-time and were capable of predicting the firing angle to explode a shell within 10 meters of a plane at anything up to 10,000 meters.〔Omega Science Digest, Nov–Dec 1983〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Allan G.
