Rosemary Allan, Senior Keeper at Beamish Museum, said: “We are delighted to have the collection here, and we’re very interested in publishing them together with information on the family plus extra interpretations.”
The artist was related to the famous Backhouse family, whose bank at Darlington was founded in 1774 and later merged with Gurney’s Bank of Norwich and Barclays of London - now known as Barclays Bank.
“The family had a tremendous influence on the railways and mining and made a huge impact at a crucial time during the industrial revolution," added Rosemary.
The album of watercolours has been presented to County Durham’s Beamish Museum by the Friends of Beamish.
