1641-1712 NEHEMIAH GREW
A botanist, who qualified as a doctor of medicine in Holland in 1664, Grew presented a paper to the Royal Society in 1684, later published in ‘Philosophical Transactions’. The paper concerned patterns of the fingers and palms, sweat pores and the epidermal ridges and their arrangements. He referred to the sweat pores as ‘little fountains’ not knowing that they would later be used in identifying criminals at crime scenes.
