Conwy Lloyd Morgan (1852-1936) was a British psychologist and ethologist known for his significant contributions to the field of comparative psychology. He is most renowned for developing the "Morgan's Canon," a guiding principle in the study of animal behavior that emphasizes parsimony and the avoidance of anthropomorphic explanations. Morgan's work in the late 19th and early 20th centuries had a profound influence on the development of psychology and the study of animal behavior.
