These papers were collected by S C B [Ben] Gascoigne who joined the staff of Mt Stromlo Observatory in 1942 after education in New Zealand and Bristol University. He retired from Mt Stromlo in 1980. His work at Mt Stromlo initially involved the production of optical munitions during the Second World War but once that finished he played a significant part in the development of Mt Stromlo Observatory as a centre for studies of the Magellanic Clouds, in the design and operation of its telescopes and in the training of astronomers at the Australian National University (ANU). From the early 1960s until 1975 he was a major player in the planning, construction and commissioning of the Anglo Australian Telescope (AAT) at Siding Spring NSW. Following his retirement in 1980 he was co-author of an official history of the AAT and wrote many pieces on the history of Australian astronomy and various astronomers he had worked with.
