John Arthur Coiley (1932–1998) was an English museum curator, principally associated with the National Railway Museum in York from its formation in the 1973-5 period, through to his retirement as keeper of the museum in 1992.
Coiley was born in West Norwood, London, and educated at Beckenham and Penge County Grammar School and later at Selwyn College, Cambridge, graduating in 1954. He was awarded a PhD in 1959 in the field of electron microscopy.[1]
He married Patricia Anne Dixon in 1956, and the couple had a daughter and two sons.[1]
Coiley's early career was outside the museum sector, working first for the UK Atomic Energy Authority, and later for two private research institutions. He joined the Science Museum in 1973 and – probably in part as a result of a lifelong interest in railway history, which included photographic contributions to Images of Steam, a 1968 publication – was appointed the first keeper of the National Railway Museum in 1974. The establishment of the museum outside London was controversial, but under Coiley's leadership proved immediately successful.[1] Over the period of his leadership, the museum "achieved a stature and authority without precedent in the fields of railway history and preservation".[2] Perhaps appropriately, the year before his retirement the NRM received the Museum of the Year Award.[2]
He was president of the International Association of Transport Museums from 1983 to 1986.[1] The Heritage Railway Association awards a John Coiley Award, for locomotive preservation.
Coiley died at Chur railway station, Switzerland on 22 May 1998 whilst on a rail tour.[1]
