Thomas Richard Fraser, toxicologist, 1884.

Etching by W Hole of Fraser, a professor at Edinburgh University. He discovered that extracts of the Calabar bean (Physostigma venenosum), introduced into the eye, caused the contraction of the pupil. He counteracted this effect by use of atropine. In 1872 he published ‘The antagonism between the actions of active substances’ in the British Medical journal. From ‘Quasi Cursores’.
