Born about 1863, he was educated at St Bartholomew's Hospital, where he served as house surgeon, and in Paris. After serving as junior house surgeon at the Wolverhampton and Staffordshire General Hospital and senior resident medical officer at the Great Northern Hospital, London, and teaching anatomy at the Durham University College of Medicine at Newcastle, Santi specialized as a laryngologist. He was senior clinical assistant at the Throat Hospital in Golden Square, and then joined the staff of the Westminster Hospital and its Medical School. He was also aural surgeon and surgeon laryngologist to St Luke's Hospital. At the Westminster Hospital, which he served for nearly thirty years, Santi was for two years surgical registrar and then senior clinical assistant in the throat department, and in due course became senior assistant surgeon in that department, and finally aural surgeon and surgeon for diseases of the throat. In the medical school he was senior demonstrator of anatomy and later lecturer in aural surgery and diseases of the nose and throat. He was senior secretary and a councillor of the Laryngological Society, before it merged in the Royal Society of Medicine in 1907. Santi was a frequent contributor to the professional journals and wrote two books. He practised at Stratford Place, W, and then had a part-time consulting room in Wimpole Street. In later years he was struck by ill-health and misfortune, and took paying-guest patients at his house in Brechin Place, South Kensington. Santi married in December 1899, and his wife survived him with a son. He died in St George's Hospital on 16 May 1942.
