An unprecedented number of people turned out for York Civic Trust’s latest blue plaque unveiling.
More than 60 people witnessed the plaque unveiling in honour of Thomas Cooke (1807-1868) on Friday, 23 August 2019, at the Observatory in the Museum Gardens, which houses one of his famous refractory telescopes.
The plaque was the co-arranged by York Civic Trust, the Yorkshire Philosophical Society and York Museums Trust, and with a good amount of representatives from each in attendance.
Thomas Cooke was an internationally-renowned Victorian optical instrument maker. Cooke built an extensive Buckingham Works factory in York’s Bishophill area in 1855, and operated as T. Cooke & Sons. The firm later moved to Haxby Road and ceased trading in 1980.
Cooke’s rotating observatory domes included those at Greenwich and Scarborough Observatories. Indeed, by the end of the century, Thomas Cooke’s domes had been built in countries throughout the world. He was elected a member of the Royal Astronomical Society in 1859.
The unveiling ceremony was marked by short speeches by Dr Peter Addyman, President of York Civic Trust; Stuart Ogilvy, Deputy Curator of Geology at the Yorkshire Museum, and Catherine Brophy, Chair of the Yorkshire Philosophical Society.
