11041 Fechner           Discovered 1989 Sept. 26 by E. W. Elst at the European Southern Observatory.
Gustav Theodor Fechner (1801-1887) was a German physicist and philosopher who founded the science of psychophysics. In his Elemente der Psychophysik (1860) he established a relation between sensations and the stimuli producing them (i.e., the "Weber-Fechner Law").
