The son of Arthur Daniel Stone, MD, by his wife, a sister of Dr John Clarke and of Sir Charles Clarke. His father, Arthur Daniel Stone, was educated at Charterhouse School and at Oxford, and was beaten for the Radcliffe Travelling Scholarship by Sir Francis Milman. Subsequently he was a Censor and Harveian Orator at the Royal College of Physicians, and Physician to the Charterhouse from 1807-1823. Thomas Arthur Stone was born in Charterhouse Square on March 3rd, 1797. He was educated at Westminster School, which he left at Bartholomewtide in 1807, and at Charterhouse from 1810-1818. He then entered at St George's Hospital, and also attended the Windmill Street School. He was Clinical Clerk to Sir Everard Home who had been an assistant to Stone's uncle, Sir Charles Mansfield Clarke, Lecturer on Midwifery and Diseases of Women. After 1821 he lectured along with Henry Davies in Windmill Street School until 1830. Later the two were appointed joint lecturers at St George's Hospital, and they lectured also at the School in Grosvenor Place. Stone was a good and popular lecturer, and in succession to his uncle, Sir Charles Mansfield Clarke, got a large practice as an accoucheur among wealthy patients, whilst continuing to practise as a general surgeon. The fashionable practice was the supposed purification of the blood by free purging and local bloodlettings. Stone continued the purging whilst giving up bleeding. He formed a museum from the previous collection of Drs Osborne, John Clarke, and Sir Charles Clarke, which he presented to St George's Hospital. He was one of the Medical Officers of Queen Charlotte's Lying-in Hospital up to the time of his death; he also acted as President of the Society for the Relief of Widows and Orphans of Medical Men, and was instrumental in obtaining the Society's Charter from Queen Victoria. Stone, although he kept notes of patients, did not take part in medical discussions, nor did he publish anything. He was kind and popular, held high views concerning professional ethics, and was a sportsman fond of exercise. He married the eldest daughter of the Rev Robert Gream, of Rotherfield, and sister of Dr Gream. This lady, distinguished for personal beauty and piety, died in 1853, leaving four sons, none of whom followed their father's profession. Stone enjoyed robust health until after an attack of 'bilious fever', from which he died at 30 Grosvenor Street, W, on August 20th, 1864.
