Matthew Dobson was an eighteenth-century physician and natural philosopher whose interests ranged far and wide but is today most remembered for what he noted when tasting his patients' urine. It was via this somewhat unpalatable experimentation that he became the first person to recognise the significance of sugar in the urine and blood of people suffering from diabetes. Diabetes had previously been thought to be a disease of the liver or kidneys but Dobson concluded that it was due to abnormal assimilation or digestion. His work was cited by John Rollo who developed dietary control of the disease towards the end of the eighteenth century.
There is a useful entry for Dobson in the Oxford Dictionary of National Biography.
