Arthur Robertson Cushny

Arthur Robertson Cushny FRS FRSE LLD (6 March 1866 – 25 February 1926), was a Scottish pharmacologist and physiologist who became a Fellow of the Royal Society.

While there he taught, conducted research and wrote his Text-Book of Pharmacology and Therapeutics, an unrivaled book for thirty years with a posthumous edition published in 1928.

He performed, with the most modern techniques of the time, the first experimental analysis of the action of digitalis on warm-blooded animals and explained its effects, thereby increasing the drug's therapeutic use and value.

He claimed that their primary structures, the glomeruli, simply filter out harmful bodily waste products while useful nutrients are reabsorbed into the body[2] in the renal tubules.

[1] Whilst in Edinburgh, he bought a historic manor house, the "Dumbiedykes" of the Heart of Midlothian, that he retired to when entertaining international medical students and physicians.
