John Saville Zamet FDS (11 November 1932 - 5 May 2007) was a periodontist in the United Kingdom. He established the first exclusively periodontal practice in London in 1966. After he retired, he attended the University College Hospital and took a course in Holocaust studies, leading him to write the biographies of refugee dental surgeons in the UK, and assess their skills as a missed opportunity for improving the ordinary quality of interwar British dental surgery. He died shortly after completing his PhD thesis on German and Austrian Refugee Dentists 1933–1945, The Response of The British Authorities in 2007. His PhD degree was awarded posthumously and his thesis remains unpublished. Early life and career John Zamet was born in London on 11 November 1932. In 1958, three years after completing his studies in dentistry at the Royal Dental Hospital (RDH), he obtained his fellowship in dental surgery of the Royal College of Surgeons of England. With an interest in periodontology, between 1956 and 1962, he worked in the departments at the Eastman Dental Hospital, Guy's Hospital and the RDH. At the time the subject was still in its infancy in the UK. Although in the US the speciality was long established, the first British academic department was only set up in 1948 at the Eastman Dental Hospital, under W. G. Cross. He went to America in 1962 on a post-graduate fellowship to study at the University of Pennsylvania Department of Periodontics. There he came under the influence of periodontologist D. Walter Cohen. Return to London and senior posts On his return to the UK, Zamet was appointed senior lecturer at the RDH, and later consultant in periodontology at University College Hospital (UCH) Dental School. After the closure of the UCH school Zamet moved to the Eastman as honorary consultant in periodontology. He stayed there until he retired in 2001. Whilst at UCH and the Eastman, Zamet carried out several research projects. In 1974 he was awarded an MPhil degree by the University of London for his dissertation, A Comparative Clinical Study of Three Periodontal Surgical techniques, which examined clinical outcomes of surgical periodontal therapy. Other research was carried out into particulate bioglass grafts. In 1966, Zamet established the first, and for many years the only, singularly periodontal practice in London. He was also the first UK periodontist to participate in the Brånemark Osseointegration Programme in Gothenburg. This programme stemmed from
