Théodore Flournoy (15 August 1854 – 5 November 1920) was a Swiss professor of psychology at the University of Geneva and author of books on parapsychology and spiritism. He studied a wide variety of subjects before he devoted his life to psychology. Flournoy had an interest in a very skeptical area of psychology. He did extensive observations on a participant to investigate psychical phenomena. He was the President of the Sixth International Congress of Psychology, the Chair of Experimental Psychology at the University of Geneva in 1891 and was the first professor of psychology in Europe to become a member of the Faculty of Sciences instead of the Faculty of Philosophy.
