Elected FRS 1967
Colin Nicol was a Canadian citizen but spent most of his working life based in the UK, at the Marine Biological Association in Plymouth, and in the USA, at the University of Texas Marine Science Institute at Port Aransas. His most important work was on the physiology of marine organisms, in particular their relationship to light, both natural and biologically produced. He was the first to show that bioluminescence is under nervous control and he made an extensive study of the tapetum lucidum, the reflective layer at the back of the eye of a wide range of animals, particularly those living in dim light. Many other subjects caught his interest and resulted in some 145 publications spanning 50 years.
