He became a member of the Corporation of Surgeons, and practised as such for some years at Lewes, Sussex.
[2] In 1761, while still an apprentice surgeon, he made his discovery of the unique and bizarre cause—compression of the oesophagus by an aberrant right subclavian artery—of a fatal case of obstructed deglutition for which he coined the term dysphagia lusoria and for which he is eponymously remembered.
This discovery remained unrecorded until 1787, when a paper describing the case was read on his behalf before the Medical Society of London.
He was elected a Fellow of the Royal Society in 1770, when he was described as a Professor of Anatomy at Surgeon's Hall; and many years Lecturer in that Science and the Operations of Surgery.
