Gustav Theodor Fechner

Born 19 Apr 1801; died 18 Nov 1887 at age 86. German physicist and philosopher who was a key figure in the founding of psychophysics, the science concerned with quantitative relations between sensations and the stimuli producing them. He formulated the rule known as Fechner's law, that, within limits, the intensity of a sensation increases as the logarithm of the stimulus. He also proposed a mathematical expression of the theory concerning the difference between two stimuli, advanced by E. H. Weber. (These are now known to be only approximately true. However, as long as the stimulus is of moderate intensity, then the laws will give us a good estimate.) Under the name "Dr. Mises" he also wrote humorous satire. In philosophy he was an animist, maintaining that life is manifest in all objects of the universe.
