Gustav Theodor Fechner

Gustav Theodor Fechner was a German philosopher, physicist, and experimental psychologist, pioneering the field of experimental psychology and founding psychophysics. His work laid the groundwork for understanding the relationship between psychological sensations and the physical intensity of stimuli. Fechner demonstrated the non-linear relationship between psychological sensation and physical stimulus intensity through a famous formula, inspiring many 20th-century scientists and philosophers. His influence extends across numerous areas of mind and perception studies.
