Gustav Fechner

Gustav Theodor Fechner (1801 to 1887) was a German physicist, philosopher and experimental psychologist. A pioneer in experimental psychology and founder of psychophysics, the techniques for measuring the mind, he inspired many twentieth century scientists and philosophers. He is also credited with demonstrating the non-linear relationship between psychological sensation and the physical intensity of a stimulus through a logarithmic formula, which became known as the Weber-Fechner law.
