In 1813, he was elected a foreign member of the Royal Swedish Academy of Sciences. On 25 August 1822, Herschel died at Observatory House, Windsor Road, Slough, after a long illness. He was buried at nearby St Laurence's Church, Upton, Slough. Herschel's epitaph is Caroline was deeply distressed by his death, and soon after his burial she returned to Hanover, a decision she later regretted. She had lived in England for fifty years. Her interests were much more in line with her nephew John Herschel, also an astronomer, than with her surviving family in Hanover.
