Richard Kershaw, chief executive of Joseph Holt Ltd, was at the unveiling ceremony. “There’s something rather appropriate about the fact that my great, great grandfather Joseph Holt walked the streets of Manchester at the same time as John Dalton,” he said. “What better way therefore, to celebrate 200 years since the birth of John Dalton, than to have a plaque honouring him on the outside of a Joseph Holt city centre pub.
“We are delighted that the Ape and Apple, which is very appropriately positioned on John Dalton Street, will bear this mark for the rest of time.“
The plaque was unveiled by David Garner, president of the Royal Society of Chemistry from 2008-2010, who said:
"I thoroughly enjoyed my return to Manchester, especially as this was to pay tribute to the great scientist, John Dalton, and unveil an RSC National Chemical Landmark plaque celebrating the 250th anniversary of his birth. This plaque is now available for the public to view on the street named after him."
Diana Leitch, was instrumental in securing a plaque to commemorate Dalton and was also present at the unveiling. Her involvement is especially fitting as she is the current president of the Manchester Literary and Philosophical Society, a position that John Dalton himself held for 28 years.
The unveiling ceremony was the culmination of a number of events held to commemorate the 250th anniversary of Dalton’s birth.
