"psycho-physics is an exact doctrine of the relation of function or dependence between body and soul" (Elemente der Psychophysik, 1860)

His law: sensation increases logarithmically with stimulus intensity.

Considered one of the founders of experimental psychology.

Merged philosophy and empirical science through measurement.

Inspired later studies of perception and thresholds.
