the biographies of refugee dental surgeons, and assessed their qualifications and skills as a missed opportunity for improving the quantity and quality of interwar British dental surgery. As a result, he established many contacts with surviving refugees and their families, assembling a unique compilation of sources. His research has been described by medical historian Paul Weindling as "outstanding" and "exceptional". Zamet compared dental training at the University of Vienna with that in Britain in the 1930s, concluding that the "dilapidated state of British dental health and dentistry" at that time was a "cottage industry". Despite demonstrating a British need for them, of the 360 Viennese dental surgeons (stomatologists) that applied to the General Medical Council (GMC) to register on the Dental Register, there being no General Dental Council until 1956, only 41 were granted registration, and only after re-certification. Many of those disallowed registration and therefore denied entry to the UK, "despite their excellent training, probably died during the Holocaust" or were led to suicide. Death and legacy Weindling attributes the loss of records and lack of archival material on migrant practitioners in general to the delay in "Vergangenheitsbewältigung", that is, the coming to terms with the past. He consequently relates Zamet as a "pioneer" in this field and a historian of refugee dental surgeons, while other medical professionals have yet to find their historian. Zamet completed his PhD thesis in December 2006. He died on 5 May 2007, and his PhD degree was awarded posthumously in 2007. In acknowledgement of his contributions to periodontology, in 2011 the London Chapter and Charitable Trust established a John Zamet Memorial Prize in Periodontal Research open to UK-based postgraduate dental students studying for a master's degree or PhD who are undertaking or who have recently completed original research associated with clinical periodontology. It is awarded every second year. Selected works Book chapters "Periodontics, the frontier" in The British Society of Periodontology, the First 50 Years, 1999.
