Less well known is who came up with the term "dialysis" in the first place. It was Thomas Graham (right), a Professor of Chemistry in Glasgow, Scotland, who ascertained that crystalloids were able to diffuse through vegetable parchment coated with albumin, which acted as a semi-permeable membrane. He coined the term "dialysis" to describe this phenomenon in 1861, and using this method was able to extract urea from urine.
A very interesting website describing some of the milestones in nephrology history can be found here.
