C. Lloyd Morgan, English zoologist and psychologist (d. 1936)
Conwy Lloyd Morgan, FRS (6 February 1852 – 6 March 1936) was a British ethologist and psychologist. He is remembered for his theory of emergent evolution, and for the experimental approach to animal psychology now known as Morgan's Canon, a principle that played a major role in behaviourism, insisting that higher mental faculties should only be considered as explanations if lower faculties could not explain a behaviour.
