Carl Stumpf

Carl Stumpf (21 April 1848 - 25 December 1936) was a philosopher and psychologist. He studied with Franz Brentano and Rudolf Hermann Lotze. He had an important influence on Edmund Husserl, the founder of modern phenomenology, Max Wertheimer, Wolfgang Köhler and Kurt Koffka, co-founders of Gestalt psychology, as well as the renowned Austrian novelist Robert Musil who was his doctoral student. Stumpf is also credited with the introduction in current philosophy of the concept of state of affairs (Sachverhalt), which was later popularised through Husserl's works. He also formed a panel of 13 eminent scientists, known as the Hans Commission, to study the claims that a horse named Clever Hans could count. Psychologist Oskar Pfungst eventually proved that the horse could not really count.
