Over the past 300 years, the medical fraternity has enthusiastically named diseases, symptoms and tests after their supposed discoverers. While some suggest that these eponyms often provide a less than truthful account of how diseases were discovered and advocate abandoning them, others argue that they should be preserved if only as a practical form of medical shorthand or aide-memoire to recall a particular disease or an association of different conditions. The purpose of this chapter is to provide the reader a brief diversion from the wearying task of absorbing the mass of information given in the preceding chapters. Listed in alphabetical order are potted biographies of some of the physicians and scientists whose names have become eponymous or synonymous with bone tumours. If nothing else, it provides a fascinating insight into medical history and reveals that physicians from many different areas of expertise have contributed to our understanding of tumours and tumour-like lesions of bone. Apologies in advance to those, alive or dead, who feel that they have been unfairly omitted from the list.
