Robert Robinson (1886-1975)

British chemist, professor in Sydney, Liverpool, St Andrews, Manchester and London and, from 1930 to 1955, at the University of Oxford. In 1917 he carried out a one-step biomimetic synthesis of tropinone, and he helped to introduce curly arrows to represent the movement of electrons in reaction mechanisms.

In 1935, with William Rapson, he described the annulation that bears his name. He received the 1947 Nobel Prize in Chemistry for his investigations on plant products of biological importance, especially the alkaloids, and was President of the Royal Society from 1945 to 1950.
