In the north choir aisle of Westminster Abbey is a white marble memorial to James Prescott Joule, physicist. The inscription reads:
"This tablet is here placed, near the graves of Newton, Herschel and Darwin, by those who in many lands have united to perpetuate the memory of James Prescott Joule F.R.S., of Manchester, in recognition of services rendered to science, in establishing the law of the conservation of energy, and determining the mechanical equivalent of heat. Born 24th December 1819, Died 11th October 1889".
He was born in Salford near Manchester, a son of Benjamin Joule and his wife Alice (Prescott). James and his brother Benjamin studied under chemist John Dalton and he went on to study electricity and electro-magnetism, working closely with Lord Kelvin. He was elected a Fellow of the Royal Society. His wife was Amelia Grimes and they had a son Benjamin and a daughter Alice. James is buried at Sale in Cheshire.
A photograph of the memorial can be purchased from Westminster Abbey Library.
